This is a note to let you know that I have just added a patch titled dmaengine: ste_dma40: fix pm runtime ref counting to the linux-3.8.y-queue branch of the 3.8.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.8.y-queue This patch is scheduled to be released in version 3.8.13.3. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.8.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From 583b34c5a1a63b0345e0e83969125e1ad0ca5ae0 Mon Sep 17 00:00:00 2001 From: Rabin Vincent <rabin.vincent@stericsson.com> Date: Mon, 27 May 2013 16:03:40 +0200 Subject: dmaengine: ste_dma40: fix pm runtime ref counting commit 9ecb41bd8cf002fd8f3e063db4df81647ddd623c upstream. The pm runtime reference counting of the driver is broken for the case when there is more than one transfer queued, leading to the device being runtime suspend while active. Fix it.
