Subject[PATCH] video/macfb: Remove redundant code
Date
The value of info->var.bits_per_pixel get checked in macfb_setcolreg().
Remove additional checks as they are redundant.

macfb_defined.activate gets initialized to FB_ACTIVATE_NOW by the struct
initializer. Remove redundant assignments.

macfb_defined.bits_per_pixel, .width and .height all get assigned
unconditionally. Remove redundant initializers.
