HID: usbhid: fix deadlock in hid_post_reset()

CVE-2026-53037

Description

In the Linux kernel, the following vulnerability has been resolved:

HID: usbhid: fix deadlock in hid_post_reset()

You can build a USB device that includes a HID component and a storage or UAS component. The components can be reset only together. That means that hid_pre_reset() and hid_post_reset() are in the block IO error handling. Hence no memory allocation used in them may do block IO because the IO can deadlock on the mutex held while resetting a device and calling the interface drivers. Use GFP_NOIO for all allocations in them.
