Hi all,
After merging the bluetooth tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:
net/bluetooth/sco.c: In function 'sco_sock_setsockopt':
net/bluetooth/sco.c:862:3: error: cannot convert to a pointer type
862 | if (get_user(opt, (u32 __user *)optval)) {
| ^~
net/bluetooth/sco.c:862:3: error: cannot convert to a pointer type
net/bluetooth/sco.c:862:3: error: cannot convert to a pointer type
Caused by commit
00398e1d5183 ("Bluetooth: Add support for BT_PKT_STATUS CMSG data for SCO connections")
interacting with commit
a7b75c5a8c41 ("net: pass a sockptr_t into ->setsockopt")
from the net-next tree.
I have applied the following merge fix patch:
