video: fbdev: omapfb_main: Mark expected switch fall-throughs
Mark switch cases where we are expecting to fall through. This patch fixes the following warning (Building: omap1_defconfig arm): drivers/watchdog/wdt285.c:170:3: warning: this statement may fall through [-Wimplicit-fallthrough=] drivers/watchdog/ar7_wdt.c:237:3: warning: this statement may fall through [-Wimplicit-fallthrough=] drivers/video/fbdev/omap/omapfb_main.c:449:23: warning: this statement may fall through [-Wimplicit-fallthrough=] drivers/video/fbdev/omap/omapfb_main.c:1549:6: warning: this statement may fall through [-Wimplicit-fallthrough=] drivers/video/fbdev/omap/omapfb_main.c:1547:3: warning: this statement may fall through [-Wimplicit-fallthrough=] drivers/video/fbdev/omap/omapfb_main.c:1545:3: warning: this statement may fall through [-Wimplicit-fallthrough=] drivers/video/fbdev/omap/omapfb_main.c:1543:3: warning: this statement may fall through [-Wimplicit-fallthrough=] drivers/video/fbdev/omap/omapfb_main.c:1540:6: warning: this statement may fall through [-Wimplicit-fallthrough=] drivers/video/fbdev/omap/omapfb_main.c:1538:3: warning: this statement may fall through [-Wimplicit-fallthrough=] drivers/video/fbdev/omap/omapfb_main.c:1535:3: warning: this statement may fall through [-Wimplicit-fallthrough=] Reviewed-by: Kees Cook <keescook@chromium.org> Signed-off-by: Gustavo A.
