Subject: [PATCH 1/3] ath6kl: cleanup ath6kl_reset_device()
Date: Fri, 08 Mar 2013 12:26:55 +0200 [thread overview]
Message-ID: <20130308102655.23245.51488.stgit@localhost6.localdomain6> (raw)
In-Reply-To: <20130308102539.23245.55176.stgit@localhost6.localdomain6>
Move it to init.c, make it static, remove all useless checks and force it to always do cold reset.
