Subject: [PATCH 10/13] spi: spi-mxs: Remove check of spi mode bits
Date: Tue, 01 Oct 2013 13:15:33 -0700 [thread overview]
Message-ID: <20131001201532.13660.90284.stgit@Graphine> (raw)
In-Reply-To: <20131001201425.13660.72740.stgit@Graphine>
The spi core already checks for a slave setting mode bits that we
didn't list as supported when the master was registered. There is no
need to do it again in the master driver.
