Dan Carpenter f8c141c3e9 nfc: signedness bug in __nci_request()
wait_for_completion_interruptible_timeout() returns -ERESTARTSYS if
interrupted so completion_rc needs to be signed.  The current code
probably returns -ETIMEDOUT if we hit this situation, but after this
patch is applied it will return -ERESTARTSYS.

Paul Gortmaker bc3b2d7fb9 net: Add export.h for EXPORT_SYMBOL/THIS_MODULE to non-modules
These files are non modular, but need to export symbols using
the macros now living in export.h -- call out the include so
that things won't break when we remove the implicit presence
of module.h from everywhere.

Dan Carpenter 8ebafde00e NFC: use after free on error
We returned a freed variable on some error paths when the intent was
to return a NULL.  Part of the reason this was missed was that the
code was confusing because it had too many gotos so I removed them
and simplified the flow a bit.

Ilan Elias de054799b7 NFC: implicitly deactivate in nci_start_poll
When start_poll is called, and a target was implicitly activated,
we need to implicitly deactivate it.
On the other hand, when the target was activated by the user,
we should not deactivate it.
