Subject: [PATCH v2 2/6] staging: fbtft: do not override DMA coherent mask
Date: Mon, 2 Jan 2017 13:35:30 +0200 [thread overview]
Message-ID: <20170102113534.127692-3-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20170102113534.127692-1-andriy.shevchenko@linux.intel.com>
Usually it's not consumer's business to override resources passed from
provider, in particularly DMA coherent mask.
