[PATCH] video: mxsfb: Fix build warnings with W=1

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@freescale.com>

Fix the following warnings when building with W=1 option:

drivers/video/mxsfb.c: In function 'mxsfb_set_par':
drivers/video/mxsfb.c:389:14: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
drivers/video/mxsfb.c: In function 'mxsfb_restore_mode':
drivers/video/mxsfb.c:592:11: warning: variable 'line_count' set but not used [-Wunused-but-set-variable]
drivers/video/mxsfb.c: In function 'mxsfb_probe':
drivers/video/mxsfb.c:867:16: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
