[PATCH 2/8] drm: renesas: rcar-du: annotate rcar_cmm_read() with __maybe_unused

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Building with clang and and W=1 leads to warning about unused
rcar_cmm_read(). Fix by annotating it with __maybe_unused.

See also commit 6863f5643dd7 ("kbuild: allow Clang to find unused static
inline functions for W=1 build").
