The set/clear of the otg control values is done writing to
two different 16bit registers, however we setup the regmap
width for isp1760/61 to 32bit value bits.
So, just access the clear register address (0x376)as the high
part of the otg control register set (0x374), and write the
values in one go to make sure they get clear/set.

If the endpoint completion callback is call right after the ep_enabled flag
is cleared and before usb_ep_dequeue() is call, we could do a double free
on the request and the associated buffer.
Fix this by clearing ep_enabled after all the endpoint requests have been
dequeued.

When the uac2 function is stopped, there seems to be an issue reported on
some platforms (Intel Merrifield at least)
BUG: kernel NULL pointer dereference, address: 0000000000000008
...
RIP: 0010:dwc3_gadget_del_and_unmap_request+0x19/0xe0
...
Call Trace:
dwc3_remove_requests.constprop.0+0x12f/0x170

afunc_set_alt+0x73/0x80 [usb_f_uac2]
composite_setup+0x224/0x1b90 [libcomposite]
The issue happens only when the gadget is using the sync type "async", not
"adaptive". This indicates that problem is coming from the feedback
endpoint, which is only used with async synchronization mode.
The problem is that request is freed regardless of usb_ep_dequeue(), which
ends up badly if the request is not actually dequeued yet.
Update the feedback endpoint free function to release the endpoint the same
way it is done for the data endpoint, which takes care of the problem.

When checking a generic status block, we iterate over all the generic data
blocks. The loop condition checks that the generic data block is valid.
Because the size of data blocks (excluding error data) may vary depending
on the revision and the revision is contained within the data block, we
should ensure that enough of the current data block is valid appropriately
for different revision.

The last two if-clauses fail to update n, so whatever they might have
written at &msg[n] would be cut off by the final nul-termination.
That nul-termination is redundant; scnprintf(), just like snprintf(),
guarantees a nul-terminated output buffer, provided the buffer size is
positive.
And there's no need to discount one byte from the initial buffer;
vsnprintf() expects to be given the full buffer size - it's not going
to write the nul-terminator one beyond the given (buffer, size) pair.

Saeed Mahameed says:
====================
This patch series contains various fixes, additions and improvements to
mlx5 software steering.
Patch 1:
adds support for REMOVE_HEADER packet reformat - a new reformat type
that is supported starting with ConnectX-6 DX, and allows removing an
arbitrary size packet segment at a selected position.
Patches 2 and 3:
add support for VLAN pop on TX and VLAN push on RX flows.
Patch 4:
enables retransmission mechanism for the SW Steering RC QP.
Patch 5:
does some improvements to error flow in building STE array and adds
a more informative printout of an invalid actions sequence.
Patch 6:
improves error flow on SW Steering QP error.
Patch 7:
reduces the log level of a message that is printed when a table is
connected to a lower/same level destination table, as this case proves to
be not as rare as it was in the past.
Patch 8:
adds missing support for matching on IPv6 flow label for devices
older than ConnectX-6 DX.
Patch 9:
replaces uintN_t types with kernel-style types.
Patch 10:
allows for using the right API for updating flow tables - if it is
a FW-owned table, then FW API will be used.
Patch 11:
adds support for 'ignore_flow_level' on multi-destination flow
tables that are created by SW Steering.
Patch 12:
optimizes FDB RX steering rule by skipping matching on source port,
as the source port for all incoming packets equals to wire.
Patch 13:
is a small code refactoring - it merges several DR_STE_SIZE enums
into a single enum.
Patch 14:
does some additional refactoring and removes HW-specific STE type
from NIC domain.
Patch 15:
removes rehash ctrl struct from dr_htbl struct and saves some memory.
Patch 16:
does a more significant improvement in terms of memory consumption
and was able to save about 1.6 Gb for 8M rules.
Patch 17:
adds support for update FTE, which is needed for cases where there
are multiple rules with the same match.

A recent restructuring of our context workaround list initialization
added an early return for non-render engines; this caused us to
potentially miss the wa_init_finish() call at the end of the function.
The mistake is pretty harmless --- the only impact is that non-render
engines on graphics version 12.50+ platforms we don't trim down the
workaround list to reclaim some memory, and we don't print the usual
"Initialized 1 context workaround" message in dmesg. Let's change the
early return to a jump down to the wa_init_finish() call at the bottom
of the function.

All callers already have a dax_device obtained from fs_dax_get_by_bdev
at hand, so just pass that to dax_supported() insted of doing another
lookup.

dax_supported calls into ->dax_supported which checks for fsdax support.
Don't bother building it for !CONFIG_FS_DAX as it will always return
false.

Just implement generic_fsdax_supported directly out of line instead of
adding a wrapper. Given that generic_fsdax_supported is only supplied
for CONFIG_FS_DAX builds this also allows to not provide it at all for
!CONFIG_FS_DAX builds.

Move the dax_read_lock/dax_read_unlock pair from the callers into
dax_supported to make it a little easier to use.
