Subject: staging: sm750fb: remove unused enable{ZVPort,SSP,PWM} functions
X-Git-Tag: firefly_0821_release~176^2~802^2~1363
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=4221c5958796174a5ea13043075816b199a60d09;p=firefly-linux-kernel-4.4.55.git

staging: sm750fb: remove unused enable{ZVPort,SSP,PWM} functions

The functions that enable/disable power for some sub-devices are not
used and therefore they can be removed.
