From 2d846fc42efeab7c963e723e69ab03ed65d8d90f Mon Sep 17 00:00:00 2001

Subject: [PATCH 06/21] spi: amd: Fix duplicate iounmap in error path
The AMD SPI driver uses devm_ioremap_resource() to map its registers, so
they're automatically unmapped via device_release() when the last ref on
the SPI controller is dropped. The additional iounmap() in the ->probe()
error path is thus unnecessary.
