Subject: staging: greybus: simplify getting .drvdata
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1dab154ef1a44933a07c0968ecd34b194ff260eb;p=linux.git

staging: greybus: simplify getting .drvdata

We should get drvdata from struct device directly. Going via
platform_device is an unneeded step back and forth.
