Subject: [PATCH 1/2] skd: Remove blk_queue_bounce_limit() call
Date: Tue, 29 Aug 2017 08:32:09 -0700	[thread overview]
Message-ID: <20170829153211.6257-2-bart.vanassche@wdc.com> (raw)
In-Reply-To: <20170829153211.6257-1-bart.vanassche@wdc.com>

Since sTec s1120 devices support 64-bit DMA it is not necessary
to request data buffer bouncing. Hence remove the
blk_queue_bounce_limit() call.
