Subject: [PATCH v2 04/13] i2c: designware-baytrail: Pass dw_i2c_dev into helper functions
Date: Mon, 23 Jan 2017 22:09:49 +0100	[thread overview]
Message-ID: <20170123210958.18410-5-hdegoede@redhat.com> (raw)
In-Reply-To: <20170123210958.18410-1-hdegoede@redhat.com>

Pass dw_i2c_dev into the helper functions, this is a preparation patch
for the punit semaphore fixes done in the other patches in this set.
