Subject: pinctrl: core: get devname from pinctrl_dev
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d6e99abb424a916ecbb127dba065a379b460a062;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

pinctrl: core: get devname from pinctrl_dev

Add new function to get devname from pinctrl_dev. pinctrl_dev_get_name()
can only get pinctrl description name. If we want to use gpio driver to
find pinctrl device node, we need to fetch the pinctrl device name.
