[ Upstream commit 3decabdc714ca56c944f4669b4cdec5c2c1cea23 ]
st21nfca_tm_send_atr_res() misses to call kfree_skb() in an error path.
Add the missed function call to fix it.

NFC: st21nfca: fix double free2019-11-12T18:13:16ZPan Bian2019-11-07T01:33:20Zurn:sha1:0c5f54da33876d187bd6baca050c7f980144248f
[ Upstream commit 99a8efbb6e30b72ac98cecf81103f847abffb1e5 ]
The variable nfcid_skb is not changed in the callee nfc_hci_get_param()
if error occurs. Consequently, the freed variable nfcid_skb will be
freed again, resulting in a double free bug. Set nfcid_skb to NULL after
releasing it to fix the bug.

NFC: st21nfca: Add support for proprietary commands2015-10-27T03:00:24ZChristophe Ricard2015-10-26T06:50:11Zurn:sha1:15d17170b4e44c5768c3d32b093cd393c4dbc158
Add support for proprietary commands useful mainly
for factory testings.
Here is a list:
- FACTORY_MODE: Allow to set the driver into a mode where no
secure element are activated. It does not consider any
NFC_ATTR_VENDOR_DATA.
- HCI_CLEAR_ALL_PIPES: Allow to execute a HCI clear all pipes
command. It does not consider any NFC_ATTR_VENDOR_DATA.
- HCI_DM_PUT_DATA: Allow to configure specific CLF registry as
for example RF trimmings or low level drivers configurations
(I2C, SPI, SWP).
- HCI_DM_UPDATE_AID: Allow to configure an AID routing into the
CLF routing table following RF technology, CLF mode or protocol.
- HCI_DM_GET_INFO: Allow to retrieve CLF information.
- HCI_DM_GET_DATA: Allow to retrieve CLF configurable data such as
low level drivers configurations or RF trimmings.
- HCI_DM_LOAD: Allow to load a firmware into the CLF. A complete
packet can be more than 8KB.
- HCI_DM_RESET: Allow to run a CLF reset in order to "commit" CLF
configuration changes without CLF power off.
- HCI_GET_PARAM: Allow to retrieve an HCI CLF parameter (for example
the white list).
- HCI_DM_FIELD_GENERATOR: Allow to generate different kind of RF
technology. When using this command to anti-collision is done.
- HCI_LOOPBACK: Allow to echo a command and test the Dh to CLF
connectivity.

NFC: st21nfca: Add error messages for unexpected HCI events2015-10-27T02:55:13ZChristophe Ricard2015-10-25T21:54:47Zurn:sha1:a9e062d0599f499082320006ae3b54cf391bf996
Potentially an unexpected HCI event may occur because of a
firmware bug. It could be transparent for the user but we should
at least log it.

A secure element can be activated in different order.
The host_list is updated keeping a fixed order:
<terminal_host_id><uicc_id><ese_id>.

It is useless to start from index 0 when looking for a gate
because only dynamic pipes are retrieved with
ST21NFCA_DM_GETINFO(ST21NFCA_DM_GETINFO_PIPE_LIST).
The first dynamic pipe is present at index 3.

We need to keep initial st_nci_gates values in order for
nfc_hci_dev_connect_gates to create and open pipe when necessary.
For example after a firmware update CLF pipes are cleared. Changing
pipe values in st21nfca_gates was causing nfc_hci_dev_connect_gates
not using accurate pipes value.
