Subject: [PATCH 6/8] drm/meson: dw-hdmi: annotate dw_hdmi_dwc_write_bits() with __maybe_unused
Date: Tue, 10 Sep 2024 13:03:42 +0300	[thread overview]
Message-ID: <fdc82abdabed667fc85d278cfb03d19e5c472d7b.1725962479.git.jani.nikula@intel.com> (raw)
In-Reply-To: <cover.1725962479.git.jani.nikula@intel.com>

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

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