I see upstream rtl8723bs driver "staging: rtl8723bs: Move wiphy setup

regulatory API misuse" fix problem.

I use rtl8723bs v5.2.17.1_26955.20180307_COEX20180201-6f52 driver, no
the "rtw_wdev_alloc(padapter, dvobj_to_dev(dvobj));"

https://github.com/youling257/rockchip_wlan/blob/v5.2.17.1/rtl8723bs/os_dep/linux/ioctl_cfg80211.h#L234
int rtw_wdev_alloc(_adapter *padapter, struct wiphy *wiphy);

https://github.com/torvalds/linux/blob/master/drivers/staging/rtl8723bs/include/ioctl_cfg80211.h#L91
int rtw_wdev_alloc(struct adapter *padapter, struct device *dev);

I want to fix rtl8723bs v5.2.17 not work problem, can you help me?

I'm not sure what your problem exactly is. If your kernel contains the

51d62f2f2c50 ("cfg80211: Save the regulatory domain with a lock")

Commit then you also need to backport (in the listed order):

81f153faacd0 ("staging: rtl8723bs: fix wireless regulatory API misuse")
50af06d43eab ("taging: rtl8723bs: Move wiphy setup to after reading the regulatory settings from the chip")

Which you seem to have already figured out ?

To keep the rtk8723bs driver working your kernel should either contain all 3 mentioned commits,
or it should contain none of them.
