Noralf Trønnes 083a6c23b9 drm/tinydrm: Clean up tinydrm_spi_transfer() ... Prep work before moving the function to mipi-dbi. tinydrm_spi_transfer() was made to support one class of drivers in drivers/staging/fbtft that has not been converted to DRM yet, so strip away the unused functionality: - Start byte (header) is not used. - No driver relies on the automatic 16-bit byte swapping on little endian machines with SPI controllers only supporting 8 bits per word. Other changes: - No need to initialize ret - No need for the WARN since mipi-dbi only uses 8 and 16 bpw. - Use spi_message_init_with_transfers() Cc: David Lechner <david@lechnology.com> Acked-by: : David Lechner <david@lechnology.com> Signed-off-by: Noralf Trønnes <noralf@tronnes.org> Link: https://patchwork.freedesktop.org/patch/msgid/20190719155916.62465-7-noralf@tronnes.org		2019-07-23 15:46:56 +02:00
