Subject: [PATCH v3 06/19] drm/panel: sitronix-st7789v: simplify st7789v_spi_write
Date: Fri, 14 Jul 2023 03:37:43 +0200	[thread overview]
Message-ID: <20230714013756.1546769-7-sre@kernel.org> (raw)
In-Reply-To: <20230714013756.1546769-1-sre@kernel.org>

st7789v_spi_write initializes a message with just
a single transfer, spi_sync_transfer can be used
for that.
