[PATCH 2/2] video: s3c-fb: fix possible division by zero in s3c_fb_calc_pixclk

From: Jingoo Han <hidden>
Date: 2012-06-11 02:27:27
Subsystem: framebuffer layer, the rest · Maintainers: Helge Deller, Linus Torvalds

Divider value can be zero and it makes division by zero
from debug message in s3c_fb_calc_pixclk; therefore, it
should be fixed.
