There is a bt power issue on Debian OS, the blueman app
will callback to enable the bluetooth power during the bringup.
As below log the system bringup about 10s.
[BT_RFKILL]: rfkill_rk_set_power: set bt wake_host pin output high!
[BT_RFKILL]: rfkill_rk_set_power: enable bt reset pin!
[BT_RFKILL]: ENABLE UART_RTS
[BT_RFKILL]: DISABLE UART_RTS
[BT_RFKILL]: bt turn on power
...
So the rfkill-bt driver should judge the power status, otherwise the
blueman app will cause the bluetoolth timeout error. e.g:
root@linaro-alip:/# bluetoothctl
[NEW] Controller 3B:A0:90:48:46:40 linaro-alip [default]
[bluetooth]# scan on

This is the mindless scripted replacement of kernel use of POLL*
variables as described by Al, done by this script:
for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do
L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
done
with de-mangling cleanups yet to come.
NOTE! On almost all architectures, the EPOLL* constants have the same
values as the POLL* constants do. But they keyword here is "almost".
For various bad reasons they aren't the same, and epoll() doesn't
actually work quite correctly in some cases due to this on Sparc et al.
The next patch from Al will sort out the final differences, and we
should be all done.

As reported by kernelci, we get a harmless warning in this driver
when CONFIG_PM is disabled:
net/rfkill/core.c:810:12: warning: 'rfkill_resume' defined but not used [-Wunused-function]
net/rfkill/core.c:800:12: warning: 'rfkill_suspend' defined but not used [-Wunused-function]
This marks the functions as __maybe_unused to remove the #ifdef, and uses
a conditional reference to the pm operations instead, which will work
in any combination.
The patch is needed for both android-common-4.9 and 4.4.

There are no users of this ("vrfkill") in the tree, so it's just
dead code - remove it.
This also isn't really how rfkill is supposed to be used - it's
intended as a signalling mechanism to/from the device, which the
driver (and partially cfg80211) will handle - having a separate
rfkill instance for a regulator is confusing, the driver should
use the regulator instead to turn off the device when requested.

This reverts commit 73f4f76a19.
As Mike reported, and I should've seen in review, we can't call
the new LED functions, which acquire the mutex, from places like
rfkill_set_sw_state() that are documented to be callable from
any context the user likes to use. For Mike's case it led to a
deadlock, but other scenarios are possible.

This requires taking rfkill_global_mutex before calling rfkill_set_block()

rfkill_set_block() unconditionally, each caller of the latter needs to
take care of locking rfkill_global_mutex.
