-Subject: [PATCH] NFC: pn533: don't send USB data off of the stack
-
-It's amazing that this driver ever worked, but now that x86 doesn't
-allow USB data to be sent off of the stack, it really does not work at
-all. Fix this up by properly allocating the data for the small
-"commands" that get sent to the device off of the stack.
-
-We do this for one command by having a whole urb just for ack messages,
-as they can be submitted in interrupt context, so we can not use
-usb_bulk_msg(). But the poweron command can sleep (and does), so use
-usb_bulk_msg() for that transfer.
