From: Greg Kroah-Hartman
Date: Tue Apr 26 2022 - 05:19:05 EST

From: Tudor Ambarus <tudor.ambarus@xxxxxxxxxxxxx>

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.
