mac80211: Update to version 5.2-rc7
as the problem behind the failure to compile batman-adv on July 21,
2019 and perhaps prior
See, for example
http://downloads.openwrt.org/snapshots/faillogs/mips_24kc/routing/batman-adv/compile.txt
/builder/shared-workdir/build/sdk/build_dir/target-mips_24kc_musl/linux-ath79_generic/batman-adv-2019.2/net/batman-adv/netlink.c:1347:4:
error: 'const struct backport_genl_ops' has no member named 'policy'
.policy = batadv_netlink_policy,
^~~~~~
Same problem observed locally on ath79 and on ipq40xx
Nothing obvious in the patch itself, but building at d616b2c906
resolves the issue for both ipq40xx and ath79 builds
Looks like the likely (upstream) event that triggered this was
(Linux) commit 3b0f31f2b8c9

genetlink: make policy common to family
which moves .policy off where "current" batman-adv is expecting it.
The backport tar ball does contain backport-include/net/genetlink.h
which seems to be picked up inappropriately for batman-adv, or there is
a patch missing for batman-adv (commit 3b0f31f2b8c9 does modify it), or ...
I haven't quite figured out how the backports work, so don't yet know
the root cause and "best" solution.
