<div class='commit-subject'>HID: cp2112: fix sleep-while-atomic</div><div class='commit-msg'>A recent commit fixing DMA-buffers on stack added a shared transfer
buffer protected by a spinlock. This is broken as the USB HID request
callbacks can sleep. Fix this up by replacing the spinlock with a mutex.
