# # Unix Domain Sockets # config UNIX tristate "Unix domain sockets" ---help--- If you say Y here, you will include support for Unix domain sockets; sockets are the standard Unix mechanism for establishing and accessing network connections. Many commonly used programs such as the X Window system and syslog use these sockets even if your machine is not connected to any network. Unless you are working on an embedded system or something similar, you therefore definitely want to say Y here. To compile this driver as a module, choose M here: the module will be called unix. Note that several important services won't work correctly if you say M here and then neglect to load the module. Say Y unless you know what you are doing. config UNIX_DIAG tristate "UNIX: socket monitoring interface" depends on UNIX default n ---help--- Support for UNIX socket monitoring interface used by the ss tool. If unsure, say Y. > net-next plumbingsTobias Klauser

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.
