-Subject: [PATCH 09/21] spi: amd: Fix refcount underflow on remove
-
-The AMD SPI driver calls spi_master_put() in its ->remove() hook even
-though the preceding call to spi_unregister_master() already drops a
-ref, thus leading to a refcount underflow.  Drop the superfluous call
-to spi_master_put().
-
-This only leaves the call to spi_unregister_master() in the ->remove()
-hook, so it's safe to change the ->probe() hook to use the devm version
-of spi_register_master() and drop the ->remove() hook altogether.
