[PATCH 0/7] NFC: fix device allocation and nfcmrvl crashes

This started out with the observation that the nfcmrvl_uart driver
unconditionally dereferenced the tty class device despite the fact that
not every tty has an associated struct device (Unix98 ptys). Some
further changes were needed in the common nfcmrvl code to fully address
this, some of which also incidentally fixed a few related bugs (e.g.
resource leaks in error paths).

While fixing this I stumbled over a regression in NFC core that lead to
broken registration error paths and misnamed workqueues.

Note that this has only been tested by configuring the n_hci line
discipline for different ttys without any actual NFC hardware connected.
