This can leave certain mailbox messages from the PF to be untreated and the PF will enter in some inactive state. If this situation occurs, the IES API will initiate a mailbox version reset which, then, trigger a mailbox state change. Once this mailbox transition occurs (from OPEN to CONNECT state), a request for reset will be returned. This ensures that PF will undergo a reset whenever IES API encounters an unknown global mailbox interrupt event or whenever the IES API terminates.

Commit adfa543e7314 ("dmatest: don't use set_freezable_with_signal()") introduced a bug (that is in fact documented by the patch commit text) that leaves behind a dangling pointer.

[Linux-stable-mirror] Patch "Bluetooth: btusb: fix QCA Rome suspend/resume" has been added to the 4.4-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled Bluetooth: btusb: fix QCA Rome suspend/resume to the 4.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: bluetooth-btusb-fix-qca-rome-suspend-resume.patch and it can be found in the queue-4.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From fd865802c66bc451dc515ed89360f84376ce1a56 Mon Sep 17 00:00:00 2001 From: Leif Liddy <leif.linux(a)gmail.com> Date: Sat, 8 Jul 2017 20:55:32 +0200 Subject: Bluetooth: btusb: fix QCA Rome suspend/resume From: Leif Liddy <leif.linux(a)gmail.com> commit fd865802c66bc451dc515ed89360f84376ce1a56 upstream. There's been numerous reported instances where BTUSB_QCA_ROME bluetooth controllers stop functioning upon resume from suspend. These devices seem to be losing power during suspend. Patch will detect a status change on resume and perform a reset.
