Variable status is set to zero but this value is never read as it is overwritten with a new value later on,clock is being assigned a value from a calculation however the variable is never read,hence these are redundant assignments that can be removed.
Clean up the following clang-analyzer warning:
drivers/gpu/drm/mgag200/mgag200_mode.c:284:3: warning: Value stored to 'clock' is never read [clang-analyzer-deadcode.DeadStores].
drivers/gpu/drm/mgag200/mgag200_mode.c:98:2: warning: Value stored to 'status' is never read [clang-analyzer-deadcode.DeadStores].
