Subject: [PATCH 03/19] gpu: drm: imx: ipuv3-plane: Mark 'crtc_state' as __always_unused
Date: Thu, 5 Nov 2020 14:45:01 +0000 [thread overview]
Message-ID: <20201105144517.1826692-4-lee.jones@linaro.org> (raw)
In-Reply-To: <20201105144517.1826692-1-lee.jones@linaro.org>
In the macro for_each_oldnew_crtc_in_state() 'crtc_state' is provided
as a container for state->crtcs[i].new_state, but is not utilised in
this use-case. We cannot simply delete the variable, so here we tell
the compiler that we're intentionally discarding the read value.
Fixes the following W=1 kernel build warning(s):
drivers/gpu/drm/imx/ipuv3-plane.c: In function ‘ipu_planes_assign_pre’:
drivers/gpu/drm/imx/ipuv3-plane.c:746:42: warning: variable ‘crtc_state’ set but not used [-Wunused-but-set-variable]
