From: Lukas Wunner lukas@wunner.de Date: Mon, 25 May 2020 14:25:03 +0200 Subject: [PATCH] spi: pxa2xx: Fix runtime PM ref imbalance on probe error

The PXA2xx SPI driver releases a runtime PM ref in the probe error path even though it hasn't acquired a ref earlier.

Apparently commit e2b714afee32 ("spi: pxa2xx: Disable runtime PM if controller registration fails") sought to copy-paste the invocation of pm_runtime_disable() from pxa2xx_spi_remove(), but erroneously copied the call to pm_runtime_put_noidle() as well. Drop it.
