Date: Wed, 29 Mar 2017 18:21:05 +0200 From: Johan Hovold <johan@...nel.org> To: Lauro Ramos Venancio <lauro.venancio@...nbossa.org>, Aloisio Almeida Jr <aloisio.almeida@...nbossa.org>, Samuel Ortiz <sameo@...ux.intel.com> Cc: linux-wireless@...r.kernel.org, netdev@...r.kernel.org, linux-kernel@...r.kernel.org, Johan Hovold <johan@...nel.org> Subject: [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.
