Series [v1,1/8] media: ov2740: Remove duplicative pointer in struct nvm_data | expand

Commit Message

Andy Shevchenko July 26, 2022, 12:05 p.m. UTC
Letting the compiler remove these functions when the kernel is built
without CONFIG_PM_SLEEP support is simpler and less heavier for builds
than the use of __maybe_unused attributes.
