From e380538529e83c5d3fd27e8cbfcc1f9799cb6bbb Mon Sep 17 00:00:00 2001 From: Rhyland Klein Date: Wed, 22 Jun 2016 11:45:52 -0400 Subject: power_supply: fix return value of get_property power_supply_get_property() should ideally return -EAGAIN if it is called while the power_supply is being registered. There was no way previously to determine if use_cnt == 0 meant that the power_supply wasn't fully registered yet, or if it had already been unregistered. Add a new boolean to the power_supply struct to simply show if registration is completed. Lastly, modify the check in power_supply_show_property() to also ignore -EAGAIN when so it doesn't complain about not returning the property.
