X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=69f1804a9ab602701217a8c23d371f8f36f8b57a;p=linux-beck.git

mei: don't use wake_up_interruptible for wr_ctrl

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:
7ff4bdd ("mei: fix waiting for wr_ctrl for corner cases.")
