For IPV6_2292PKTOPTIONS, do_ipv6_getsockopt() stores the user pointer
optval in the msg_control field of the msghdr.
Hence, sparse rightfully warns at ./net/ipv6/ipv6_sockglue.c:1151:33:

'st->ext_ref' & 'st->reg' are both non-zero/non-null at the same time, so
logically the code isn't broken.
But it is more correct to check that 'st->reg' is non-null, since we make
sure that the regulator is NULL (in probe) in case one isn't defined.

This change converts the probe of this driver to use device-managed
register functions, and a devm_add_action_or_reset() for the regulator
disable.
With this, the exit & error paths can be removed.
Another side-effect is that this should avoid some static-analyzer's check

Use pm_runtime_resume_and_get to fix it.
