From 2a9123f185ca07dcd76f36242ee03bed3fe2ab5c Mon Sep 17 00:00:00 2001 From: Vaishali Thakkar Date: Thu, 17 Sep 2015 18:03:40 +0530 Subject: [PATCH] 88pm860x_battery: Convert to using managed resources Use managed resource functions devm_request_threaded_irq and devm_power_supply_register to simplify error handling. To be compatible with the change, various gotos are replaced with direct returns and unneeded labels are dropped. Also, remove pm860x_battery_remove as it is now redundant.
