Subject: [PATCH v2 06/13] drm/panel: sitronix-st7789v: simplify st7789v_spi_write
Date: Sat, 22 Apr 2023 22:50:05 +0200 [thread overview]
Message-ID: <20230422205012.2464933-7-sre@kernel.org> (raw)
In-Reply-To: <20230422205012.2464933-1-sre@kernel.org>
st7789v_spi_write initializes a message with just
a single transfer, spi_sync_transfer can be used
for that.
