Subject: [PATCH v2] video: fbdev: Mark expected switch fall-through
Date: Tue, 30 Jul 2019 15:25:30 +0000 [thread overview]
Message-ID: <20190730152530.3055-1-anders.roxell@linaro.org> (raw)
Now that -Wimplicit-fallthrough is passed to GCC by default, the
following warnings shows up:
../drivers/video/fbdev/sh_mobile_lcdcfb.c: In function ‘sh_mobile_lcdc_channel_fb_init’:
../drivers/video/fbdev/sh_mobile_lcdcfb.c:2086:22: warning: this statement may fall
through [-Wimplicit-fallthrough=]
info->fix.ypanstep = 2;
~~~~~~~~~~~~~~~~~~~^~~
../drivers/video/fbdev/sh_mobile_lcdcfb.c:2087:2: note: here
case V4L2_PIX_FMT_NV16:
^~~~
../drivers/video/fbdev/sh_mobile_lcdcfb.c: In function ‘sh_mobile_lcdc_overlay_fb_init’:
../drivers/video/fbdev/sh_mobile_lcdcfb.c:1596:22: warning: this statement may fall
through [-Wimplicit-fallthrough=]
info->fix.ypanstep = 2;
~~~~~~~~~~~~~~~~~~~^~~
../drivers/video/fbdev/sh_mobile_lcdcfb.c:1597:2: note: here
case V4L2_PIX_FMT_NV16:
^~~~
Rework to address a warnings due to the enablement of
-Wimplicit-fallthrough.
