Integer variable 'identical' is being initialized however this value is never read as 'identical' is assigned the result of 'start + (width - end)'. Remove the redundant assignment. At the same time, adjust the declarations order of variables to keep the "upside-down x-mas tree" look of them.

Clean up clang warning:

drivers/video/fbdev/udlfb.c:370:6: warning: Value stored to 'identical' during its initialization is never read [clang-analyzer-deadcode.DeadStores]
