Subject: [PATCH 3/3] mwifiex: use del_timer variant in interrupt context
Date: Thu, 12 Mar 2015 00:38:40 -0700 [thread overview]
Message-ID: <1426145920-5288-3-git-send-email-akarwar@marvell.com> (raw)
In-Reply-To: <1426145920-5288-1-git-send-email-akarwar@marvell.com>
We might be in interrupt context at few places. So replace
del_timer_sync() with del_timer(). This patch fixes a kernel
trace problem seen occasionally during our testing.
