From 2b88cd96eb85d2f07873e6050e531df45d8a0cc8 Mon Sep 17 00:00:00 2001 From: Sudip Mukherjee Date: Sun, 12 Jun 2016 15:05:29 +0100 Subject: tpm: use devm_add_action_or_reset If devm_add_action() fails we are explicitly calling put_device() to free the resources allocated. Lets use the helper devm_add_action_or_reset() and return directly in case of error, as we know that the cleanup function has been already called by the helper if there was any error.
