Subject: staging: sm750fb: remove unused macros
X-Git-Tag: firefly_0821_release~176^2~802^2~1365
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=6af70030431d5d58b34c294ddb371baf7f6c9d4b;p=firefly-linux-kernel-4.4.55.git

staging: sm750fb: remove unused macros

Several macros defined in sm750.h and sm750_help.h are not used and
therefore they can be removed
