Subject: [PATCH 03/14] spi: axi-spi-engine: simplify driver data allocation
Date: Fri, 17 Nov 2023 14:12:54 -0600 [thread overview]
Message-ID: <20231117-axi-spi-engine-series-1-v1-3-cc59db999b87@baylibre.com> (raw)
In-Reply-To: <20231117-axi-spi-engine-series-1-v1-0-cc59db999b87@baylibre.com>
This simplifies the private data allocation in the AXI SPI Engine driver
by making use of the feature built into the spi_alloc_host() function
instead of doing it manually.
