do this type of thing. :-)

Actually ieee80211_assign_chanctx() checks if local->use_chanctx is
true, so this patch doesn't change the logic. I should mentioned it in
the commit log.

Return NOTIFY_DONE if we don't care this time's notification, return
NOTIFY_OK if we successfully handled this time's notification. That's
the formal way to do it.

ieee80211_assign_chanctx() checks if local->use_chanctx is true, so
the two code block related to ieee80211_assign_chanctx() can be moved

local->use_chanctx is true.

But this means these messages go away by default now, why would we want
that?

Both wiphy_debug() and wiphy_dbg() are used in mac80211. Change
wiphy_debug() to wiphy_dbg() so all the debug messages can be
dynamically controled whether to be generated or not.

Oh, you're right. Please also split the patch into two.

Works rdev->rfkill_sync and rdev->sched_scan_results_wk are safely
stopped when unregistering wiphy.
Work reg_regdb_work is safely stopped in regulatory_exit(), if related
config option is enabled.
Queue work cfg80211_disconnect_work to workqueue cfg80211_wq, since
it's a work owned by cfg80211, and so it can be safely stopped in
destroy_workqueue(cfg80211_wq) in cfg80211_exit().
Change flush_work() to more robust cancel_work_sync().

Change "err" to "ret", since return value isn't zero doesn't always
mean error occured, sometimes it means success.
if (err)
/* do things if function successfully returned */
looks strange to me, so change it.
This change related to the functions which call
cfg80211_chandef_dfs_check(), since cfg80211_chandef_dfs_check()
returns 1 means dfs is required.

Applied.

Name "dev" is too common and ambiguous, let all the pointer name

improve code readability and consistency(since other places have
already called it rdev).

It's in the hotpath though, so we don't always want it, it's mostly for
development that this matters.
I don't think I want to apply this patch.

Change the name to cfg80211_chandef_dfs_check to emphasize that the
function isn't a bool function, its return value must be fully
checked.
Also rename the helper function's name to
cfg80211_do_chandef_dfs_check for consistency.
Variable width in cfg80211_chandef_dfs_check() needn't to be checked
for sanity, since above cfg80211_chandef_valid() already checked the
sanity of chandef->width.
Since cfg80211.h is touched, also correct a typo in comment.

Btw, it was a bit confusing that you sent your older patches in this
patchset again, please avoid that or at least tell me you did that.
