Pull USB fixes from Greg KH: "Here are three small USB fixes for reported problems for 5.13-rc7. They include: - disable autosuspend for a cypress USB hub - fix the battery charger detection for the chipidea driver - fix a kernel panic in the dwc3 driver due to a previous change in 5.13-rc1. All have been in linux-next with no reported problems" * tag 'usb-5.13-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: usb: core: hub: Disable autosuspend for Cypress CY7C65632 usb: chipidea: imx: Fix Battery Charger 1.2 CDP detection usb: dwc3: core: fix kernel panic when do reboot
