[PATCH] media: imx: remove code for non-existing config IMX_GPT_ICAP

[PATCH] media: imx: remove code for non-existing config IMX_GPT_ICAP

[Lukas Bulwahn]

There never was a config IMX_GPT_ICAP in the repository. So remove the code
conditional on this config and simplify the callers that just called empty
functions.

As suggested by the checkpatch.pl:

Strangely, my checkpatch invocation on next-20221116 did not show that
warning and I am unaware that I made any specific changes to
checkpatch or its configuration.

Anyway, checkpatch and you, Tommaso, are right and the patch can of
course be improved. I sent out a patch v2:

https://lore.kernel.org/all/20221123075216.28193-1-lukas.bulwahn@gmail.com/

I hope to get an Acked-by: tag from you now. Thanks.

Lukas

I think you need to apply the patch and retest with the -f option.
