From 380603712072145785f19040b9791f4f6cde414e Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Wed, 5 Mar 2014 15:17:23 +0800 Subject: [PATCH] spi: s3c24xx: Add missing spi_master_{resume,suspend} calls to PM callbacks This is required since commit 2025172e3280 "spi/bitbang: Use core message pump". spi-bitbang now uses core message pump, so it needs to call spi_master_suspend/ spi_master_resume to start/stop the queue while suspend/resume.
