Instead of using the legacy GPIO API and keeping track on
polarity inversion semantics in the driver, switch to use
GPIO descriptors for this driver and change all consumers
in the process.
This makes it possible to retire platform data completely:
the only remaining platform data member was "wakeup" which
was intended to make the vbus interrupt wakeup capable,
but was not set by any users and thus remained unused. VBUS
was not waking any devices up. Leave a comment about it so
later developers using the platform can consider setting it
to always enabled so plugging in USB wakes up the platform.

Use a synchronous usb_bulk_msg() when switching link speed in
set_termios(). This way we do not need to keep track of outstanding URBs
in order to be able to stop them at close.
Note that there's no need to set URB_ZERO_PACKET as the one-byte
transfer will always be short.

Commit f4a4cbb2047e ("USB: ir-usb: reimplement using generic framework")
switched to using the generic write implementation which may combine
multiple write requests into larger transfers. This can break the IrLAP
protocol where end-of-frame is determined using the USB short packet
mechanism, for example, if multiple frames are sent in rapid succession.

Commit e0d795e4f36c ("usb: irda: cleanup on ir-usb module") added a USB
IrDA header with common defines, but mistakingly switched to using the
class-descriptor baud-rate bitmask values for the outbound header.
This broke link-speed handling for rates above 9600 baud, but a device
would also be able to operate at the default 9600 baud until a
link-speed request was issued (e.g. using the TCGETS ioctl).

Add missing endpoint sanity check to avoid dereferencing a NULL-pointer
on open() in case a device lacks a bulk-out endpoint.
Note that prior to commit f4a4cbb2047e ("USB: ir-usb: reimplement using
generic framework") the oops would instead happen on open() if the
device lacked a bulk-in endpoint and on write() if it lacked a bulk-out
endpoint.

T6 can support 2 egress traffic management channels per port to
double the total number of traffic classes that can be configured.
In this configuration, if the class belongs to the other channel,
then all the queues must be bound again explicitly to the new class,
for the rate limit parameters on the other channel to take effect.
So, always explicitly bind all queues to the port rate limit traffic
class, regardless of the traffic management channel that it belongs
to. Also, only bind queues to port rate limit traffic class, if all
the queues don't already belong to an existing different traffic
class.

Pull thread fixes from Christian Brauner:
"Here is an urgent fix for ptrace_may_access() permission checking.
Commit 69f594a38967 ("ptrace: do not audit capability check when
outputing /proc/pid/stat") introduced the ability to opt out of audit
messages for accesses to various proc files since they are not
violations of policy.
While doing so it switched the check from ns_capable() to
has_ns_capability{_noaudit}(). That means it switched from checking
the subjective credentials (ktask->cred) of the task to using the
objective credentials (ktask->real_cred). This is appears to be wrong.
ptrace_has_cap() is currently only used in ptrace_may_access() And is
used to check whether the calling task (subject) has the
CAP_SYS_PTRACE capability in the provided user namespace to operate on
the target task (object). According to the cred.h comments this means
the subjective credentials of the calling task need to be used.
With this fix we switch ptrace_has_cap() to use security_capable() and
thus back to using the subjective credentials.
As one example where this might be particularly problematic, Jann
pointed out that in combination with the upcoming IORING_OP_OPENAT{2}
feature, this bug might allow unprivileged users to bypass the
capability checks while asynchronously opening files like /proc/*/mem,
because the capability checks for this would be performed against
kernel credentials.
To illustrate on the former point about this being exploitable: When
io_uring creates a new context it records the subjective credentials
of the caller. Later on, when it starts to do work it creates a kernel
thread and registers a callback. The callback runs with kernel creds
for ktask->real_cred and ktask->cred.
To prevent this from becoming a full-blown 0-day io_uring will call
override_cred() and override ktask->cred with the subjective
credentials of the creator of the io_uring instance. With
ptrace_has_cap() currently looking at ktask->real_cred this override
will be ineffective and the caller will be able to open arbitray proc
files as mentioned above.
Luckily, this is currently not exploitable but would be so once
IORING_OP_OPENAT{2} land in v5.6. Let's fix it now.
To minimize potential regressions I successfully ran the criu
testsuite. criu makes heavy use of ptrace() and extensively hits
ptrace_may_access() codepaths and has a good change of detecting any
regressions.
Additionally, I succesfully ran the ptrace and seccomp kernel tests"

3 small bug fix patches. The 1st two are aRFS fixes and the last one
fixes a fatal driver load failure on some kernels without PCIe
extended config space support enabled.
Please also queue these for -stable. Thanks.

DSN read can fail, for example on a kdump kernel without PCIe extended
config space support. If DSN read fails, don't set the
BNXT_FLAG_DSN_VALID flag and continue loading. Check the flag
to see if the stored DSN is valid before using it. Only VF reps
creation should fail without valid DSN.
