fbdev: au1200fb: Fix potential divide by zero
[ Upstream commit 44a3b36b ] var->pixclock can be assigned to zero by user. Without proper check, divide by zero would occur when invoking macro PICOS2KHZ in au1200fb_fb_check_var. Error out if var->pixclock is zero. Signed-off-by:Wei Chen <harperchen1110@gmail.com> Signed-off-by:
