No, if a driver has:
	config foo
	depends on HAS_IOMEM
	select I2C

the select will only be handled if HAS_IOMEM. It won't bypass HAS_IOMEM
(and if it is bypassing, then there's some regression at the building
system, and lots of other things would break).

Also, changing from select to depends on I2C_MUX is not nice for users,
as it is not intuitive that a driver would need such core support for
a media driver to work.

Here, everything is OK. No need to convert it to depends on.

So, just this should be enough to fix the dependencies for HAS_IOMEM/I2C_MUX
at the drivers under drivers/media:

diff --git a/drivers/media/usb/cx231xx/Kconfig b/drivers/media/usb/cx231xx/Kconfig
index 0cced3e5b040..67d21b026054 100644
