      vfs: do bulk POLL* -> EPOLL* replacement · a9a08845
      Linus Torvalds authored
      This is the mindless scripted replacement of kernel use of POLL*
      variables as described by Al, done by this script:
      
          for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do
              L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
              for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
          done
      
      with de-mangling cleanups yet to come.
      
      NOTE! On almost all architectures, the EPOLL* constants have the same
      values as the POLL* constants do.  But they keyword here is "almost".
      For various bad reasons they aren't the same, and epoll() doesn't
      actually work quite correctly in some cases due to this on Sparc et al.
      
      The next patch from Al will sort out the final differences, and we
      should be all done.

      media: pci: Convert timers to use timer_setup() · 162e6376
      Kees Cook authored
      In preparation for unconditionally passing the struct timer_list pointer to
      all timer callbacks, switch to using the new timer_setup() and from_timer()
      to pass the timer pointer explicitly.

      [media] bt8xx: don't break long lines · 652fd6ea
      Mauro Carvalho Chehab authored
      Due to the 80-cols restrictions, and latter due to checkpatch
      warnings, several strings were broken into multiple lines. This
      is not considered a good practice anymore, as it makes harder
      to grep for strings at the source code.
      
      As we're right now fixing other drivers due to KERN_CONT, we need
      to be able to identify what printk strings don't end with a "\n".
      It is a way easier to detect those if we don't break long lines.
      
      So, join those continuation lines.
      
      The patch was generated via the script below, and manually
      adjusted if needed.
      
      </script>
      use Text::Tabs;
      while (<>) {
      	if ($next ne "") {
      		$c=$_;
      		if ($c =~ /^\s+\"(.*)/) {
      			$c2=$1;
      			$next =~ s/\"\n$//;
      			$n = expand($next);
      			$funpos = index($n, '(');
      			$pos = index($c2, '",');
      			if ($funpos && $pos > 0) {
      				$s1 = substr $c2, 0, $pos + 2;
      				$s2 = ' ' x ($funpos + 1) . substr $c2, $pos + 2;
      				$s2 =~ s/^\s+//;
      
      				$s2 = ' ' x ($funpos + 1) . $s2 if ($s2 ne "");
      
      				print unexpand("$next$s1\n");
      				print unexpand("$s2\n") if ($s2 ne "");
      			} else {
      				print "$next$c2\n";

      [media] include/media: move driver interface headers to a separate dir · d647f0b7
      Mauro Carvalho Chehab authored
      Let's not mix headers used by the core with those headers that
      are needed by some driver-specific interface header.
      
      The headers used on drivers were manually moved using:
          mkdir include/media/drv-intf/
          git mv include/media/cx2341x.h include/media/cx25840.h \
      	include/media/exynos-fimc.h include/media/msp3400.h \
      	include/media/s3c_camif.h include/media/saa7146.h \
      	include/media/saa7146_vv.h  include/media/sh_mobile_ceu.h \
      	include/media/sh_mobile_csi2.h include/media/sh_vou.h \
      	include/media/si476x.h include/media/soc_mediabus.h \
      	include/media/tea575x.h include/media/drv-intf/
      
      And the references for those headers were corrected using:
      
          MAIN_DIR="media/"
          PREV_DIR="media/"
          DIRS="drv-intf/"
      
          echo "Checking affected files" >&2
          for i in $DIRS; do
      	for j in $(find include/$MAIN_DIR/$i -type f -name '*.h'); do
      		 n=`basename $j`
      		git grep -l $n
      	done
          done|sort|uniq >files && (
      	echo "Handling files..." >&2;
      	echo "for i in \$(cat files|grep -v Documentation); do cat \$i | \\";
      	(
      		cd include/$MAIN_DIR;
      		for j in $DIRS; do

      [media] include/media: split I2C headers from V4L2 core · b5dcee22
      Mauro Carvalho Chehab authored
      Currently, include/media is messy, as it contains both the V4L2 core
      headers and some driver-specific headers on the same place. That makes
      harder to identify what core headers should be documented and what
      headers belong to I2C drivers that are included only by bridge/main
      drivers that would require the functions provided by them.
      
      Let's move those i2c specific files to its own subdirectory.
      
      The files to move were produced via the following script:
      	mkdir include/media/i2c
      	(cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done)
      	(cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/*/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done)
      	for i in include/media/*.h; do n=`basename $i`;  (for j in $(git grep -l $n); do dirname $j; done)|sort|uniq|grep -ve '^.$' > list; num=$(wc -l list|cut -d' ' -f1); if [ $num == 1 ]; then if [ "`grep i2c list`" != "" ]; then git mv $i include/media/i2c; fi; fi; done
      
      And the references corrected via this script:
          MAIN_DIR="media/"
          PREV_DIR="media/"
          DIRS="i2c/"
      
          echo "Checking affected files" >&2
          for i in $DIRS; do
      	for j in $(find include/$MAIN_DIR/$i -type f -name '*.h'); do
      		 n=`basename $j`
      		git grep -l $n
      	done
          done|sort|uniq >files && (
      	echo "Handling files..." >&2;
      	echo "for i in \$(cat files|grep -v Documentation); do cat \$i | \\";
      	(
      		cd include/$MAIN_DIR;
      		for j in $DIRS; do
      			for i in $(ls $j); do
      				echo "perl -ne 's,(include [\\\"\\<])$PREV_DIR($i)([\\\"\\>]),\1$MAIN_DIR$j\2\3,; print \$_' |\\";
      			done;
      		done;
      		echo "cat > a && mv a \$i; done";
      	);
      	echo "Handling documentation..." >&2;
      	echo "for i in MAINTAINERS \$(cat files); do cat \$i | \\";
      	(
      		cd include/$MAIN_DIR;
      		for j in $DIRS; do
      			for i in $(ls $j); do
      				echo "  perl -ne 's,include/$PREV_DIR($i)\b,include/$MAIN_DIR$j\1,; print \$_' |\\";
      			done;
      		done;
      		echo "cat > a && mv a \$i; done"
      	);
          ) >script && . ./script
      
      Merged Sakari Ailus patch that moves smiapp.h to include/media/i2c.

      [media] [REGRESSION] bt8xx: Fix too large height in cropcap · 35ccecef
      Hans de Goede authored
      Since commit a1fd2877:
      "[media] bttv-driver: fix two warnings"
      cropcap.defrect.height and cropcap.bounds.height for the PAL entry are 32
      resp 30 pixels too large, if a userspace app (ie xawtv) actually tries to use
      the full advertised height, the resulting image is broken in ways only a
      screenshot can describe.
      The cause of this is the fix for this warning:
      drivers/media/pci/bt8xx/bttv-driver.c:308:3: warning: initialized field overwritten [-Woverride-init]
      In this chunk of the commit:
      @@ -301,11 +301,10 @@ const struct bttv_tvnorm bttv_tvnorms[] = {

                      .name           = "NTSC",
      Which replaces the overriding of cropcap.bounds.height initialization outside
      of the CROPCAP macro (which also initializes it), with passing a
      different sheight value to the CROPCAP macro.
      There are 2 problems with this warning fix:
      1) The sheight value is used twice in the CROPCAP macro, and the old code
         only changed one resulting value.
      2) The old code increased the .cropcap.bounds.height value (and did not
         touch the .cropcap.defrect.height value at all) by 2, where as the fixed
         code increases it by 32, as the fixed code passes (576 + 2) + 0x20 - 2
         to the CROPCAP macro, but the + 0x20 - 2 is already done by the macro so
         now is done twice for .cropcap.bounds.height, and also is applied to
         .cropcap.defrect.height where it should not be applied at all.
      This patch fixes this by adding an extraheight parameter to the CROPCAP entry
      and using it for the PAL entry.
