2019-08-26v4l2-core: fix coding style for the two new c filesMauro Carvalho Chehab
As I2C and SPI parts of the V4L2 core got split, let's take the chance and solve the CodingStyle issues there, as reported by checkpatch --strict. Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
2019-08-26media: v4l2-core: Remove BUG() from i2c and spi helpersEzequiel Garcia
Currently, the i2c and spi subdev creation helpers are calling BUG() when passed a NULL v4l2_device parameter. This makes little sense; simply returning NULL seems more sensible. These two helpers may already return NULL on error, so callers should already be checking for this, or at least be prepared for a NULL result.

2019-08-26media: v4l2-core: introduce a helper to unregister a i2c subdevEzequiel Garcia
Introduce a new video4linux2 i2c helper, to unregister a subdev. This allows to get rid of yet another ifdef.

2019-08-26media: v4l2-core: move i2c helpers out of v4l2-common.cEzequiel Garcia
Separate the i2c helpers to v4l2-i2c.c, in order to get rid of the ifdefery. No functional changes intended, this is just a cosmetic change to organize the code better. Given I2C is a tristate symbol, a hidden boolean symbol is introduced, to make the conditional build easier.
