/**
 * struct caif_dev_common - data shared between CAIF drivers and stack.
 * @flowctrl:		Flow Control callback function. This function is
 *                      supplied by CAIF Core Stack and is used by CAIF
 *                      Link Layer to send flow-stop to CAIF Core.
 *                      The flow information will be distributed to all
 *                      clients of CAIF.
 *
 * @link_select:	Profile of device, either high-bandwidth or
 *			low-latency. This member is set by CAIF Link
 *			Layer Device in	order to indicate if this device
 *			is a high bandwidth or low latency device.
 *
 * @use_frag:		CAIF Frames may be fragmented.
 *			Is set by CAIF Link Layer in order to indicate if the
 *			interface receives fragmented frames that must be
 *			assembled by CAIF Core Layer.
 *
 * @use_fcs:		Indicate if Frame CheckSum (fcs) is used.
 *			Is set if the physical interface is
 *			using Frame Checksum on the CAIF Frames.
 *
 * @use_stx:		Indicate STart of frame eXtension (stx) in use.
 *			Is set if the CAIF Link Layer expects
 *			CAIF Frames to start with the STX byte.
 *
 * This structure is shared between the CAIF drivers and the CAIF stack.
 * It is used by the device to register its behavior.
 * CAIF Core layer must set the member flowctrl in order to supply
 * CAIF Link Layer with the flow control function.

<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.
