	---help---
	  IEEE Std 802.15.4 defines a low data rate, low power and low
	  complexity short range wireless personal area networks. It was
	  designed to organise networks of sensors, switches, etc automation
	  devices. Maximum allowed data rate is 250 kb/s and typical personal
	  operating space around 10m.

	  Say Y here to compile LR-WPAN support into the kernel or say M to
	  compile it as modules.

HID: cp2112: fix sleep-while-atomic
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.
