Subject: build failure of next-20220811 due to 332f1795ca20 ("Bluetooth: L2CAP: Fix l2cap_global_chan_by_psm regression")

Hi All,
Not sure if it has been reported, builds of csky and mips allmodconfig
failed to build next-20220811 with gcc-12.
mips error is:
In function 'memcmp',
inlined from 'bacmp' at ./include/net/bluetooth/bluetooth.h:347:9,
inlined from 'l2cap_global_chan_by_psm' at net/bluetooth/l2cap_core.c:2003:15:

git bisect pointed to 332f1795ca20 ("Bluetooth: L2CAP: Fix l2cap_global_chan_by_psm regression").
And, reverting that commit has fixed the build failure.
I will be happy to test any patch or provide any extra log if needed.
