pci_endpoint_test_doorbell() reads the BAR number directly from an endpoint
test register and uses it as an index into test->bar[]. Add a defensive
bounds check before the dereference: positive values >= PCI_STD_NUM_BARS
are out of range, and NO_BAR (-1) as a negative signed value would slip
past an upper-bound-only check.

Pull staging driver updates from Greg KH:
"Here is the big set of staging driver updates for 7.2-rc1.
Nothing major in here, just constant grind of tiny cleanups and coding
style fixes and wrapper removals. Overall more code was removed than
added, always a nice sign that things are progressing forward.
Changes outside of drivers/staging/ was due to the octeon driver
changes, which for some reason also lives partially in the mips
subsystem, someday that all will be untangled and cleaned up, or just
removed entirely, it's hard to tell which is going to be its fate.
Other than octeon driver cleanups, in here are the usual:
- rtl8723bs driver reworking and cleanups, being the bulk of this
merge window given all of the issues and wrappers involved in that
beast of a driver
- most driver cleanups
- sm750fb driver cleanups (which might be done, as this really should
be moved to the drm layer one of these days...)
- other tiny staging driver cleanups and fixes
All of these have been in linux-next for many weeks with no reported
issues"

Since multiple OA streams might be open in parallel on a gt, ensure that
proper locking is in place. Also ensure that OA registers are whitelisted
when the first OA stream is open and de-whitelisted after the last OA
stream is closed.

Whitelist OA registers on stream open and de-whitelist on stream
close/release. Whitelisting is only done when 'stream->sample' is
true. 'stream->sample' is only true when (a) xe_observation_paranoid is set
to false by system admin, or (b) the process is perfmon_capable(). This
therefore enforces the OA register whitelisting security requirements.

Whitelist or de-whitelist OA registers for all hwe's on the gt on which the
OA stream is opened. This simplifies the case where an oa unit has 0
attached hwe's (but which monitors OA events on the associated GT).

Now we can save OA whitelisting nonpriv registers to register save/restore
lists. OA nonpriv registers are saved to both hwe->oa_sr as well as
hwe->reg_sr.
During probe, resume and gt-reset flows KMD will apply hwe->reg_sr,
ensuring OA registers are de-whitelisted after these events. For
engine-reset, hwe->reg_sr is registered with GuC and GuC will apply these
registers, ensuring OA registers are de-whitelisted after engine resets.
hwe->oa_sr is used for whitelisting or de-whitelisting OA registers during
OA operation, by toggling the 'deny' bit on oa stream open/close.

The driver allocates domain generic chips using
irq_alloc_domain_generic_chips() during probe and sets up chained
handlers using irq_set_chained_handler_and_data(). However, on driver
removal, the generic chips are not freed and the chained handlers are
not removed.
The generic chips remain on the global gc_list and may later be accessed by
generic interrupt chip suspend, resume, or shutdown callbacks after the
driver has been removed, potentially resulting in a use-after-free and
kernel crash.
The chained handlers that were installed in probe for peripheral and
syswake interrupts are also left dangling, which can lead to spurious
interrupts accessing freed memory.
Fix these issues by:
- Setting IRQ_DOMAIN_FLAG_DESTROY_GC flag in domain->flags, so the
core code automatically removes generic chips when irq_domain_remove()
is called
- Clearing all chained handlers with NULL in pdc_intc_remove()
