patch "usb: gadget: aspeed: fix stop dma register setting." added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled usb: gadget: aspeed: fix stop dma register setting. 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.

patch "USB: ehci: fix an interrupt calltrace error" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled USB: ehci: fix an interrupt calltrace error 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. >From 643a4df7fe3f6831d14536fd692be85f92670a52 Mon Sep 17 00:00:00 2001 From: Longfang Liu <liulongfang(a)huawei.com> Date: Tue, 12 Jan 2021 09:57:27 +0800 Subject: USB: ehci: fix an interrupt calltrace error The system that use Synopsys USB host controllers goes to suspend when using USB audio player. This causes the USB host controller continuous send interrupt signal to system, When the number of interrupts exceeds 100000, the system will forcibly close the interrupts and output a calltrace error. When the system goes to suspend, the last interrupt is reported to the driver. At this time, the system has set the state to suspend. This causes the last interrupt to not be processed by the system and not clear the interrupt flag. This uncleared interrupt flag constantly triggers new interrupt event. This causing the driver to receive more than 100,000 interrupts, which causes the system to forcibly close the interrupt report and report the calltrace error. so, when the driver goes to sleep and changes the system state to suspend, the interrupt flag needs to be cleared.
