adding the new mtd_master class, because it entirely fails the
partitioning if a specific Kconfig option is set. We need to think how
to handle that differently, so let's revert it as we need to get back to
the pen and paper situation again.
Otherwise the definition of some Winbond SPI NAND chips are receiving
some fixes (geometry and maximum frequency, mostly).
And finally a small memory leak gets also fixed.

Pull SCSI fixes from James Bottomley:
"Two small and obvious driver fixes"
* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
scsi: elx: efct: Fix memory leak in efct_hw_parse_filter()
scsi: target: Fix NULL pointer dereference in core_scsi3_decode_spec_i_port()
Currently the call_rcu() API does not check whether a callback
pointer is NULL. If NULL is passed, rcu_core() will try to invoke
it, resulting in NULL pointer dereference and a kernel crash.
To prevent this and improve debuggability, this patch adds a check
for NULL and emits a kernel stack trace to help identify a faulty
caller.

The multi message support loosened the connection between the request
and response handling, as we can now submit multiple requests before
we start processing responses. Passing the attr set to NlMsgs decoding
no longer makes sense (if it ever did), attr set may differ message
by messsage. Isolate the part of decoding responsible for attr-set
specific interpretation and call it once we identified the correct op.
Without this fix performing SET operation on an ethtool socket, while
being subscribed to notifications causes:
# File "tools/net/ynl/pyynl/lib/ynl.py", line 1096, in _op
# Exception| return self._ops(ops)[0]
# Exception| ~~~~~~~~~^^^^^
# File "tools/net/ynl/pyynl/lib/ynl.py", line 1040, in _ops
# Exception| nms = NlMsgs(reply, attr_space=op.attr_set)
# Exception| ^^^^^^^^^^^
The value of op we use on line 1040 is stale, it comes form the previous
loop. If a notification comes before a response we will update op to None
and the next iteration thru the loop will break with the trace above.

Setting tty->disc_data before opening the NCI device means we need to
clean it up on error paths. This also opens some short window if device
starts sending data, even before NCIUARTSETDRIVER IOCTL succeeded
(broken hardware?). Close the window by exposing tty->disc_data only on
the success path, when opening of the NCI device and try_module_get()
succeeds.
The code differs in error path in one aspect: tty->disc_data won't be
ever assigned thus NULL-ified. This however should not be relevant
difference, because of "tty->disc_data=NULL" in nci_uart_tty_open().

When the GuC fails to load we declare the device wedged. However, the
very first GuC load attempt on GT0 (from xe_gt_init_hwconfig) is done
before the GT1 GuC objects are initialized, so things go bad when the
wedge code attempts to cleanup GT1. To fix this, check the initialization
status in the functions called during wedge.

Before calling lan743x_ptp_io_event_clock_get(), the 'channel' value
is checked against the maximum value of PCI11X1X_PTP_IO_MAX_CHANNELS(8).
This seems correct and aligns with the PTP interrupt status register
(PTP_INT_STS) specifications.
However, lan743x_ptp_io_event_clock_get() writes to ptp->extts[] with
only LAN743X_PTP_N_EXTTS(4) elements, using channel as an index:
lan743x_ptp_io_event_clock_get(..., u8 channel,...)
{
...
/* Update Local timestamp */
extts = &ptp->extts[channel];
extts->ts.tv_sec = sec;
...
}
To avoid an out-of-bounds write and utilize all the supported GPIO
inputs, set LAN743X_PTP_N_EXTTS to 8.
Detected using the static analysis tool - Svace.

net: fix passive TFO socket having invalid NAPI ID
Found a bug where an accepted passive TFO socket returns an invalid NAPI
ID (i.e. 0) from SO_INCOMING_NAPI_ID. Add a selftest for this using
netdevsim and fix the bug.
Patch 1 is a drive-by fix for the lib.sh include in an existing
drivers/net/netdevsim/peer.sh selftest.
Patch 2 adds a test binary for a simple TFO server/client.
Patch 3 adds a selftest for checking that the NAPI ID of a passive TFO
socket is valid. This will currently fail.
Patch 4 adds a fix for the bug.

There is a bug with passive TFO sockets returning an invalid NAPI ID 0
from SO_INCOMING_NAPI_ID. Normally this is not an issue, but zero copy
receive relies on a correct NAPI ID to process sockets on the right
queue.
Fix by adding a sk_mark_napi_id_set().
