[ Upstream commit ecc443c03fb14abfb8a6af5e3b2d43b5257e60f2 ] pn533_recv_response() is an urb completion handler, so it must use GFP_ATOMIC. pn533_usb_send_frame() OTOH runs from a regular sleeping context, so the pn533_submit_urb_for_response() there (and only there) can use the regular GFP_KERNEL flags.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
