Subject: phonedev: remove BKL
X-Git-Tag: v2.6.28-rc1~166
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=60c11d2abf4ef811d0ce3ea34279746729c4c6fc;p=platform%2Fkernel%2Flinux-3.10.git

phonedev: remove BKL

The phone_device array is covered by the phone_lock mutex in all cases and
request_module no longer needs the BKL so we can remove the only remaining
instance of the BKL from phonedev.
