[PATCH -next v4] drm/i2c: tda998x: remove redundant CONFIG_OF and of_match_ptr()

From: Zhu Wang
Date: Fri Aug 04 2023 - 07:07:03 EST


The driver depends on CONFIG_OF, so it is not necessary to use CONFIG_OF
and of_match_ptr() here, we remove them all.

Even for drivers that do not depend on CONFIG_OF, it's almost always
better to leave out the of_match_ptr(), since the only thing it can
possibly do is to save a few bytes of .text if a driver can be used both
with and without it.
