    gpio: pass lookup and descriptor flags to request_own · 5923ea6c
    Linus Walleij authored
    When a gpio_chip wants to request a descriptor from itself
    using gpiochip_request_own_desc() it needs to be able to specify
    fully how to use the descriptor, notably line inversion
    semantics. The workaround in the gpiolib.c can be removed
    and cases (such as SPI CS) where we need at times to request
    a GPIO with line inversion semantics directly on a chip for
    workarounds, can be fully supported with this call.
    Fix up some users of the API that weren't really using the
    last flag to set up the line as input or output properly
    but instead just calling direction setting explicitly
    after requesting the line.
