Subject: [PATCH 2/2] drm: sun4i: tcon: Mark expected switch fall-through
Date: Fri, 26 Jul 2019 13:28:07 +0200 [thread overview]
Message-ID: <20190726112807.19615-1-anders.roxell@linaro.org> (raw)
When fall-through warnings was enabled by default the following warning
was starting to show up:
../drivers/gpu/drm/sun4i/sun4i_tcon.c: In function ‘sun4i_tcon0_mode_set_dithering’:
../drivers/gpu/drm/sun4i/sun4i_tcon.c:316:7: warning: this statement may fall
through [-Wimplicit-fallthrough=]
val |= SUN4I_TCON0_FRM_CTL_MODE_B;
../drivers/gpu/drm/sun4i/sun4i_tcon.c:317:2: note: here
case MEDIA_BUS_FMT_RGB666_1X18:
^~~~
Rework so that the compiler doesn't warn about fall-through.
Fixes: d93512ef0f0e ("Makefile: Globally enable fall-through warning")
