When only the instructions event is requested:

M builtin-stat.c
Performance counter stats for 'git s':
917,453,420 instructions # 0.00 insns per cycle
0.213002926 seconds time elapsed
The 0.00 insns per cycle comment in the output is totally bogus and
misleading. It happens because update_shadow_stats() doesn't touch
runtime_cycles_stats when only the instructions event is requested. So,
omit printing the bogus data altogether.

Plus adding default rule for INITIAL condition. This prevents default

Patch be1a4b brought some improvements to the GPIO error handling code,
but also changed the return value of gpiod_request() when called on a
not yet initialized GPIO descriptor: it now returns -EINVAL instead of
-EPROBE_DEFER, and this affects some drivers.
This patch restores the original behavior for gpiod_request(). It is
safe to do so now that desc_to_gpio() does not rely on the GPIO
descriptor to be initialized. Other functions changed by patch be1a4b
do not see their return value affected, so these are not reverted.

The current implementation of desc_to_gpio() relies on the chip pointer
to be set to a valid value in order to compute the GPIO number. This
was done in the hope that we can get rid of the gpio_desc global array,
but this is not happening anytime soon.
This patch reimplements desc_to_gpio() in a fashion similar to that of
gpio_to_desc(). As a result, desc_to_gpio(gpio_to_desc(gpio)) == gpio is
now always true. This allows to call desc_to_gpio() on non-initialized
descriptors as some error-handling code currently does.

descriptor is now splitted into maximum packet size value and number of
additional transaction per microframe.
- Modify s3c_hsotg_write_fifo() function. It actually calculates transfer

transactions per microframe.

If we have a wiphy with an ISO3166-alpha2 regulatory domain
programmed with the strict flag set we wait until the wiphy
gets its wiphy->regd programmed before allowing regulatory
domains hints other than country IE hints from processing
on the wiphy. The existing check however discards the
possibility of custom regulatory domains having also used
the strict flag and these will not have the wiphy->regd
set. Custom strict regulatory domains never set the wiphy->regd
though as such currently all regulatory hints other than
country IE hints are being ignored on these wiphys.
All custom strict regulatory domains set the wiphy with the
WIPHY_FLAG_CUSTOM_REGULATORY and use wiphy_apply_custom_regulatory().
Enhance the check for the strict ISO3166-alpha2 regulatory domain
case by exempting the WIPHY_FLAG_CUSTOM_REGULATORY case. This
will enable other regulatory hints to be processed now for
these strict custom regulatory domains.
