[PATCH 0/7] Fix divide errors in fbdev drivers

[Zheyu Ma]

None of these framebuffer drivers checks for 'pixclock', leading to many
divide errors, which we fix by checking the value of 'pixclock' in
*_check_var(). As discussed before, it is better to keep the check per
driver rather than in the caller.
