The mutex for the regulator_dev must be controlled by the caller of the regulator_notifier_call_chain(), as described in the comment for that function. Failure to mutex lock and unlock surrounding the notifier call results in a kernel WARN_ON_ONCE() which will dump a backtrace for the regulator_notifier_call_chain() when that function call is first made. The mutex can be controlled using the regulator_lock/unlock() API. Fixes: 1028a37d ("regulator: da9211: new regulator driver") Suggested-by:

The only user of wm8400_block_read/wm8400_set_bits functions is the wm8400 regulator driver. At the context of all the callers, we can use regmap_bulk_read/regmap_update_bits directly. Thus remove wm8400_block_read/wm8400_set_bits functions. Signed-off-by:

When IPv6 is compiled but disabled at runtime, geneve_sock_add returns -EAFNOSUPPORT. For metadata based tunnels, this causes failure of the whole operation of bringing up the tunnel. Ignore failure of IPv6 socket creation for metadata based tunnels caused by IPv6 not being available. This is the same fix as what commit d074bf96 ("vxlan: correctly handle ipv6.disable module parameter") is doing for vxlan. Note there's also commit c0a47e44 ("geneve: should not call rt6_lookup() when ipv6 was disabled") which fixes a similar issue but for regular tunnels, while this patch is needed for metadata based tunnels.

When debugging another issue I faced an interrupt storm in this driver (88E6390, port 9 in SGMII mode), consisting of alternating link-up / link-down interrupts. Analysis showed that the driver wanted to set a cmode that was set already. But so far mv88e6390x_port_set_cmode() doesn't check this and powers down SERDES, what causes the link to break, and eventually results in the described interrupt storm. Fix this by checking whether the cmode actually changes. We want that the very first call to mv88e6390x_port_set_cmode() always configures the registers, therefore initialize port.cmode with a value that is different from any supported cmode value. We have to take care that we only init the ports cmode once chip->info->num_ports is set. v2: - add small helper and init the number of actual ports only Fixes: 364e9d77 ("net: dsa: mv88e6xxx: Power on/off SERDES on cmode change") Signed-off-by:
