You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >>From 8ebe9d163e93e10458f3fd7522f29f9149e58632 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Thu, 3 Sep 2015 22:40:53 +0200 Subject: [PATCH] spi: s3c64xx: replace clock disabling with runtime PM suspend call in remove function Simplify s3c64xx_spi_remove by replacing the clock disabling with calling runtime PM suspend which does the same. Waking up the device if it was suspended wouldn't be strictly needed for this driver but using pm_runtime_get_sync is cleaner and makes s3c64xx_spi_remove more consistent with the runtime PM handling in s3c64xx_spi_setup. pm_runtime_force_suspend does most of the work for us: disabling the clocks, disabling runtime PM and setting it to "suspended" state.
