Commit 81f153faac ("staging: rtl8723bs: fix wireless regulatory API
misuse") moved the wiphy_apply_custom_regulatory() call to earlier in the
driver's init-sequence, so that it gets called before wiphy_register().
But at this point in time the eFuses which code the regulatory-settings
for the chip have not been read by the driver yet, causing
_rtw_reg_apply_flags() to set the IEEE80211_CHAN_DISABLED flag on *all*
channels.
On the device where I initially tested the fix, a Jumper EZpad 7 tablet,
this does not cause any problems because shortly after init the
rtw_reg_notifier() gets called fixing things up. I guess this happens
into response to receiving a (broadcast) packet with regulatory info
from the access-point ?
But on another device with a RTL8723BS wifi chip, an Acer Switch 10E
(SW3-016), the rtw_reg_notifier() never gets called. I assume that some
fuse has been set on this device to ignore regulatory info received from
access-points.
This means that on the Acer the driver is stuck in a state with all
channels disabled, leading to non working Wifi.
We cannot move the wiphy_apply_custom_regulatory() call back, because
that call must be made before the wiphy_register() call.
Instead move the entire rtw_wdev_alloc() call to after the Efuses have
been read, fixing all channels being disabled in the initial channel-map.

This code ends up calling wiphy_apply_custom_regulatory(), for which
we document that it should be called before wiphy_register(). This
driver doesn't do that, but calls it from ndo_open() with the RTNL
held, which caused deadlocks.
Since the driver just registers static regdomain data and then the
notifier applies the channel changes if any, there's no reason for
it to call this in ndo_open(), move it earlier to fix the deadlock.
