I thought i broke something when building imx8-current-librem5 but then it was the camera:

drivers/media/i2c/hi846.c: In function ‘hi846_set_format’:

Would be coo to have fixed since this makes one miss errors in local builds. @martin.kepplinger since you're on that driver, could you fix that please?
