So each driver have to add ifdefs around those helpers or add the CONFIG_VIDEO_V4L2_SUBDEV_API as dependcy. Make these helpers available in case of CONFIG_VIDEO_V4L2_SUBDEV_API isn't set to avoid ifdefs. This approach is less error prone too. Signed-off-by: Marco Felsch --- The patch was previously part of series [1]. Since I want to get series [1] merged in 5.2 I split this possible stopper out of the serie and prepared a own series for it. I applied Jacopos comments and switched to Lubomir's approach [2]. During discussion on series [2] Sakari pointed out Hans approach [3] which didn't got into the kernel due to Mauro's concerns. So I think this would be the smalles common dennominator.
