From 168d7c4e8bb25c076ed8be67fcca84f5dcd0b2c6 Mon Sep 17 00:00:00 2001 From: John Youn Date: Tue, 31 May 2016 16:55:01 -0700 Subject: reset: Return -ENOTSUPP when not configured Prior to commit 6c96f05c8bb8 ("reset: Make [of_]reset_control_get[_foo] functions wrappers"), the "optional" functions returned -ENOTSUPP when CONFIG_RESET_CONTROLLER was not set. 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.
