[ Upstream commit 1c34890273a020d61d6127ade3f68ed1cb21c16a ]
of_node_put() should have been done directly after
mqs_priv->regmap = syscon_node_to_regmap(gpr_np);
otherwise it creates a reference leak on the success path.
To fix this, of_node_put() is moved to the correct location, and change
all the gotos to direct returns.
