Subject: leds-lp55xx: clean up unused data and functions
X-Git-Tag: upstream/snapshot3+hdmi~5648^2~10
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=93ca4093adb757d5140071e72b2e9bfbb519b6c1;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

leds-lp55xx: clean up unused data and functions

 Old data structures and I2C function are not used any more.
 Each driver uses the lp55xx common data and functions.
