    Subject[PATCH 5.15 122/124] spi: atmel-quadspi: Fix the buswidth adjustment between spi-mem and controller
    Date
    From: Tudor Ambarus <tudor.ambarus@microchip.com>

    commit 8c235cc25087495c4288d94f547e9d3061004991 upstream.

    Use the spi_mem_default_supports_op() core helper in order to take into
    account the buswidth specified by the user in device tree.
