Subject: [PATCH 1/7] spi: fsi: Handle 9 to 15 byte transfers lengths
Date: Thu, 20 Aug 2020 12:02:22 -0500	[thread overview]
Message-ID: <20200820170228.42053-2-eajames@linux.ibm.com> (raw)
In-Reply-To: <20200820170228.42053-1-eajames@linux.ibm.com>

From: Brad Bishop <bradleyb@fuzziesquirrel.com>

The trailing <len> - 8 bytes of transfer data in this size range is no
longer ignored.
