Bluetooth: btusb: Use GFP_KERNEL in btusb_send_frame()
All hdev->send() calls are these days done through a work queue. For the btusb driver this means the btusb_send_frame() function. Because of this we can safely use GFP_KERNEL for all memory allocations in this code path. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
