Subject: [char-misc-next 1/2] mei: don't use wake_up_interruptible for wr_ctrl
Date: Mon, 9 May 2016 00:07:46 -0400 [thread overview]
Message-ID: <1462766867-27248-1-git-send-email-tomas.winkler@intel.com> (raw)
From: Alexander Usyskin <alexander.usyskin@intel.com>
wr_ctrl waiters are none interruptible, so should be waken up
with call to wake_up and not to wake_up_interruptible.
This fixes commit:
