From 8d5b5d5ce58ee1b90110f4e358eefe3c3a6b08a2 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Sun, 1 May 2016 19:36:57 +0900 Subject: reset: add devm_reset_controller_register API Add a device managed API for reset_controller_register(). This helps in reducing code in .remove callbacks and sometimes dropping .remove callbacks entirely.

Revert back to the old behavior by changing the new __devm_reset_control_get() and __of_reset_control_get() functions to return ERR_PTR(-ENOTSUPP) when compiled without CONFIG_RESET_CONTROLLER. Otherwise they will return -EINVAL causing users to think that an error occurred when CONFIG_RESET_CONTROLLER is not set.
