Dual-role switch (ID, OTG FSM, sysfs), Host-only, and
Peripheral-only.
When compiled dynamically, the module will be called ci-hdrc.ko.

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.
Fixes: 1ffb3c40ffb5 ("HID: cp2112: make transfer buffers DMA capable")
