Subject: rfkill: add type string helper
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=99c632e5a304e1f76350eb9e8b2493514de8b60c;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

rfkill: add type string helper

We will need access to the rfkill switch type in string format for more
than just sysfs.  Therefore, move it to a generic helper.
