[LINUX PATCH 2/3] spi: spi-mem: call spi_mem_default_supports_op() first

[Naga Sureshkumar Relli <naga.sureshkumar.relli@xxxxxxxxxx>]

Call spi_mem_default_supports_op() first, before calling controller
specific ctlr->supports_op().
With this, controller drivers can drop checking the buswidths again.
