linux-next: manual merge of the net-next tree with the staging tree

From: Stephen Rothwell
Date: Sun Aug 29 2021 - 21:42:52 EST

Hi all,

Today's linux-next merge of the net-next tree got a conflict in:

drivers/staging/rtl8723bs/os_dep/ioctl_linux.c

between commit:

174ac41a7aaf ("staging: rtl8723bs: remove obsolete wext support")

from the staging tree and commit:

89939e890605 ("staging: rtlwifi: use siocdevprivate")

from the net-next tree.

I fixed it up (see below - though it is probably better to get rid of
rtw_siocdevprivate() as well) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging. You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Cheers,
Stephen Rothwell
