[7/8] media: atomisp: add return codes for pipeline config functions

Message ID 4c53ca49a2787065e42c322865a9f0417b944b99.1636134411.git.mchehab+huawei@kernel.org (mailing list archive)

Series [1/8] media: atomisp: drop duplicated ia_css_isp_configs.c | expand

Commit Message

Mauro Carvalho Chehab Nov. 5, 2021, 5:48 p.m. UTC
Those functions can internally break, but, as they don't return
errors, internally there are some assert() calls, which is bad,
as it hangs the driver.

So, add return codes there, in preparation for removing such
assert() calls.
