Subject: [PATCH v5 12/13] spi: mxic: Use spi_mem_generic_supports_op()
Date: Tue, 14 Dec 2021 12:41:39 +0100	[thread overview]
Message-ID: <20211214114140.54629-13-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20211214114140.54629-1-miquel.raynal@bootlin.com>

This driver can be simplified a little bit by using
spi_mem_generic_supports_op() instead of the
spi_mem_default/dtr_supports_op() couple. The all_false boolean is
inverted to become a dtr boolean, which checks if at least one of the
operation member uses dtr mode. The idea behind this change is to
simplify the introduction of the pipelined ECC engine.
