+Subject: [PATCH 2/2] spi: bcm63xx-hsspi: fix pm_runtime
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The driver sets auto_runtime_pm to true, but it doesn't call
+pm_runtime_enable(), which results in "Failed to power device" when PM support
+is enabled.
