Subject: [PATCH 1/6] usb: dwc3: st: fix dma initialization
Date: Sat, 2 Apr 2016 11:28:54 +0300 [thread overview]
Message-ID: <1459585739-21204-2-git-send-email-felipe.balbi@linux.intel.com> (raw)
In-Reply-To: <1459585739-21204-1-git-send-email-felipe.balbi-VuQAYsv1563Yd54FQh9/CA@public.gmane.org>
Current code was basically a no-op. As it was
initializing dev->coherent_dma_mask with
dev->coherent_dma_mask. Due to lack of more
information, just initialize it to a 32-bit mask.
