X-Git-Tag: upstream/snapshot3+hdmi~14653^2~44^2~34
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=45cdba4d376adfd30cfbda1b7d43110818d967cc;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

Input: uinput - remove BKL from uinput_open function

Commit 8702965848ed4bee27486a3e3d2ae34ebba6dd83 pushed down the BKL
into uinput open function. However, there's nothing that needs locking
in there.
