Subject: [PATCH 03/12] spi: spi-fsl-dspi: Don't mask off undefined bits
Date: Thu,  5 Mar 2020 00:00:35 +0200	[thread overview]
Message-ID: <20200304220044.11193-4-olteanv@gmail.com> (raw)
In-Reply-To: <20200304220044.11193-1-olteanv@gmail.com>

From: Vladimir Oltean <vladimir.oltean@nxp.com>

This is a useless operation, and if the driver needs to do that, there's
something deeply wrong going on.
