Subject: media: cx25821: drop duplicated i2c_slave_did_ack()
Author:  Mauro Carvalho Chehab <mchehab+hua...@kernel.org>
Date:    Mon Nov 22 08:24:03 2021 +0000

This function is defined twice, one at cx25821-i2c and the other
inside cx25821-core. It turns that only the first
is actually used inside the code.

This causes a clang warning.
