catc_ctrl_run() calls usb_submit_urb() with GFP_KERNEL, while it is called from catc_ctrl_async() and catc_ctrl_done() with catc->ctrl_lock spinlock held. The patch replaces GFP_KERNEL with GFP_ATOMIC. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by: Alexey Khoroshilov <redacted>
Applied.
