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:

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.
