Subject: [PATCH] fbdev/fb.h: silence warning with -Wsign-compare

Silence the warning when building with -Wsign-compare when fb.h is
included:

include/linux/fb.h: In function ‘__fb_pad_aligned_buffer’:
include/linux/fb.h:650:17: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
   for (j = 0; j < s_pitch; j++)
                 ^
