Subject: pda_power: add init and exit function callbacks
X-Git-Tag: Ubuntu-5.2.0-15.16~35738^2~1
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=f6b6b180b4614e57af217045f71caedd94821fc7;p=mirror_ubuntu-eoan-kernel.git

pda_power: add init and exit function callbacks

This adds init/exit function callbacks to pda_power, to
provide a place where the platform code can request/free
GPIOs that it wants to use in the is_ac_online, is_usb_online
and set_charge functions.
