---help---
MultiProtocol Label Switching routes packets through logical
circuits. Originally conceived as a way of routing packets at
hardware speeds (before hardware was capable of routing ipv4 packets),
MPLS remains a simple way of making tunnels.
If you have not heard of MPLS you probably want to say N here.
if MPLS
config NET_MPLS_GSO
tristate "MPLS: GSO support"
help
This is helper module to allow segmentation of non-MPLS GSO packets
that have had MPLS stack entries pushed onto them and thus
become MPLS GSO packets.
config MPLS_ROUTING
tristate "MPLS: routing support"
---help---
Add support for forwarding of mpls packets.
config MPLS_IPTUNNEL
tristate "MPLS: IP over MPLS tunnel support"
depends on LWTUNNEL && MPLS_ROUTING
---help---
mpls ip tunnel support.

regulator: gpio: properly check return value of of_get_named_gpio
The function of_get_named_gpio() could return -ENOENT, -EPROBE_DEFER
-EINVAL and so on. Currently, for the optional property "enable-gpio",
we only check -EPROBE_DEFER, this is not enough since there may be
misconfigured "enable-gpio" in the DTB, of_get_named_gpio() will return
-EINVAL in this case, we should return immediately here. And for the
optional property "gpios", we didn't check the return value, the driver
will continue to the point where gpio_request_array() is called, it
doesn't make sense to continue if we got -EPROBE_DEFER or -EINVAL here.
This patch tries to address these two issues by properly checking the
return value of of_get_named_gpio.
