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.

In order to align with st21nfca, dts configuration properties
ese_present and uicc_present are made available in st-nci driver.
So far, in early development firmware, because
nci_nfcee_mode_set(DISABLE) was not supported we had to try to
enable it during the secure element discovery phase.
After several trials on commercial and qualified firmware it appears
that nci_nfcee_mode_set(ENABLE) and nci_nfcee_mode_set(DISABLE) are
properly supported.
Such feature also help us to eventually save some time (~5ms) when
only one secure element is connected.

The commit 1bab0de0274f ("dm-mpath, scsi_dh: don't let dm detach device
handlers") removed reference counting of attached scsi device handler.
As a result, handler data is freed immediately via scsi_dh->detach()
in the context of scsi_remove_device() where activation request can be
still in flight.
This patch moves scsi_dh_handler_detach() to sdev releasing function,
scsi_device_dev_release_usercontext(), at that point the device
is already in quiesced state.

When pci_pool_alloc fails in mvs_task_prep then task->lldd_task stays
NULL but it's later used in mvs_abort_task as slot which is passed
to mvs_slot_task_free causing NULL pointer dereference.
Just return from mvs_slot_task_free when passed with NULL slot.

The "compatible" matching algorithm used for looking up old-style
blacklist entries in a scsi_dev_info_list is buggy. The core of the
algorithm looks like this:
if (memcmp(devinfo->vendor, vendor,
min(max, strlen(devinfo->vendor))))
/* not a match */
where max is the length of the device's vendor string after leading
spaces have been removed but trailing spaces have not. Because of the
min() computation, either entry could be a proper substring of the
other and the code would still think that they match.
In the case originally reported, the device's vendor and product
strings were "Inateck " and " ". These matched against
the following entry in the global device list:
{"", "Scanner", "1.80", BLIST_NOLUN}
because "" is a substring of "Inateck " and "" (the result of removing
leading spaces from the device's product string) is a substring of
"Scanner". The mistaken match prevented the system from scanning and
finding the device's second Logical Unit.
This patch fixes the problem by making two changes. First, the code
for leading-space removal is hoisted out of the loop. (This means it
will sometimes run unnecessarily, but since a large percentage of all
lookups involve the "compatible" entries in global device list, this
should be an overall improvement.) Second and more importantly, the
patch removes trailing spaces and adds a check to verify that the two
resulting strings are exactly the same length. This prevents matches
where one entry is a proper substring of the other.

scsi_get_device_flags_keyed() routines contain a large amount of
duplicate code for finding vendor/product matches in a

While the current driver mostly supports BCM7445 which has a hardcoded
location for its MoCA port on port 7 and port 0 for its internal PHY,
this is not necessarily true for all other chips out there such as
BCM3390 for instance.
Walk the list of ports from Device Tree, get their port number ("reg"
property), and then parse the "phy-mode" property and initialize two
internal variables: moca_port and a bitmask of internal PHYs. Since we
use interrupts for the MoCA port, we introduce two helper functions to
enable/disable interrupts and do this at the appropriate bank (INTRL2_0
or INTRL2_1).

This patch allows the LPFC to start up without a fatal kernel bug based
on an exceeded KMALLOC_MAX_SIZE and a too large NR_CPU-based maskbits
field. The bug was based on the number of CPU cores in a system.
Using the get_cpu_mask() function declared in kernel/cpu.c allows the
driver to load on the community kernel 4.2 RC1.
Below is the kernel bug reproduced:

Currently the module parameter lpfc_sg_seg_count does not have effect
for sli3 devices.
In lpfc_sli_driver_resource_setup(), which is used for sli3, the code
writes the configured sg_seg_cnt into lpfc_template.sg_tablesize.
But lpfc_template is the template used for sli4 only. Thus the value should
correctly be written to lpfc_template_s3->sg_tablesize.
This patch is for kernel 4.1-rc5, but is tested with lpfc 10.2.405.26 only.

Having a traceable function in the sched_clock() path leads to a recursion
within ftrace and a kernel crash.
We should not trace digicolor_timer_sched_read() function. Fix this by adding
the notrace attribute to this function.

button bits
commit 92bac83dd79e ("Input: alps - non interleaved V2 dualpoint has
separate stick button bits") assumes that all alps v2 non-interleaved
dual point setups have the separate stick button bits.
Later we limited this to Dell laptops only because of reports that this
broke things on non Dell laptops. Now it turns out that this breaks things
on the Dell Latitude D600 too. So it seems that only the Dell Latitude
D420/430/620/630, which all share the same touchpad / stick combo,
have these separate bits.
This patch limits the checking of the separate bits to only these models
fixing regressions with other models.
