video: fbdev: s3c-fb: Mark expected switch fall-throughs
In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warnings: drivers/video/fbdev/s3c-fb.c: In function ‘s3c_fb_blank’: drivers/video/fbdev/s3c-fb.c:811:16: warning: this statement may fall through [-Wimplicit-fallthrough=] sfb->enabled &= ~(1 << index); ~~~~~~~~~~~~~^~~~~~~~~~~~~~~~ drivers/video/fbdev/s3c-fb.c:814:2: note: here case FB_BLANK_NORMAL: ^~~~ LD [M] drivers/staging/greybus/gb-light.o CC [M] drivers/gpu/drm/nouveau/nvkm/subdev/secboot/gp10b.o drivers/video/fbdev/s3c-fb.c: In function ‘s3c_fb_check_var’: drivers/video/fbdev/s3c-fb.c:286:22: warning: this statement may fall through [-Wimplicit-fallthrough=] var->transp.length = 1; ~~~~~~~~~~~~~~~~~~~^~~ drivers/video/fbdev/s3c-fb.c:288:2: note: here case 18: ^~~~ drivers/video/fbdev/s3c-fb.c:314:22: warning: this statement may fall through [-Wimplicit-fallthrough=] var->transp.offset = 24; ~~~~~~~~~~~~~~~~~~~^~~~ drivers/video/fbdev/s3c-fb.c:316:2: note: here case 24: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 Notice that, in this particular case, the code comments are modified in accordance with what GCC is expecting to find. This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough. Signed-off-by: Gustavo A. R.
