in kgsl_pwrscale_init(), add missing NULL check for kgsl_midframe
to avoid further accessing, in case if memory is not available.

Enable retention of memory and periphery logics for
GPU core clock. If the setting is not done then GPU
might get stale data while switching from NAP to
ACTIVE and which leads to page faults or hangs.
Clock settings need to be handled by client drivers only
and hence do it in KGSL driver.

On sdm660, VDDIO needs 1.8V and LDO11 is voted for 1.88V
which is causing higher power numbers. Update the vote
correctly for LDO11.

This exports a new cfg80211_stop_iface() function.
This is intended for driver internal interface
combination management and channel switching.
Due to locking issues (it re-enters driver) the
call is asynchronous and uses cfg80211 event
list/worker.

Qualcomm Technologies Inc vendor specific wlan driver (qcacld-3.0)
internally supports wow mode and is enabled by default.
Currently, cfg80211 subsystem and wpa_supplicant is not aware of
qcacld-3.0 internal support for wowlan, due to which wpa_supplicant
is issuing disconnect on suspend, resulting in wowlan failure.
To fix this, avoid disconnect on suspend.

Below is the synchronization issue between unmount and kjournald2
contexts, which results into use after free issue in kjournald2().
Fix this issue by using journal->j_state_lock to synchronize the
wait_event() done in journal_kill_thread() and the wake_up() done
in kjournald2().
TASK 1:
umount cmd:
|--jbd2_journal_destroy() {
|--journal_kill_thread() {
write_lock(&journal->j_state_lock);
journal->j_flags |= JBD2_UNMOUNT;
...
write_unlock(&journal->j_state_lock);
wake_up(&journal->j_wait_commit); TASK 2 wakes up here:
kjournald2() {
...
checks JBD2_UNMOUNT flag and calls goto end-loop;
...
end_loop:
write_unlock(&journal->j_state_lock);
journal->j_task = NULL; --> If this thread gets
pre-empted here, then TASK 1 wait_event will
exit even before this thread is completely
done.
wait_event(journal->j_wait_done_commit, journal->j_task == NULL);
...
write_lock(&journal->j_state_lock);
write_unlock(&journal->j_state_lock);
}
|--kfree(journal);
}
}
wake_up(&journal->j_wait_done_commit); --> this step
now results into use after free issue.
}
