This is a note to let you know that I've just added the patch titled
usb: musb: Fix suspend with devices connected for a64
to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch.
The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.
If you have any questions about this process, please let me know.

Pinephone running on Allwinner A64 fails to suspend with USB devices connected as reported by Bhushan Shah bshah@kde.org. Reverting commit 5fbf7a253470 ("usb: musb: fix idling for suspend after disconnect interrupt") fixes the issue.
Let's add suspend checks also for suspend after disconnect interrupt quirk handling like we already do elsewhere.
