mfd: syscon: Don't free allocated name for regmap_config
[ Upstream commit 529a110 ] The name allocated for the regmap_config structure is freed pretty early, right after the registration of the MMIO region. Unfortunately, that doesn't follow the life cycle that debugfs expects, as it can access the name field long after the free has occurred. Move the free on the error path, and keep it forever otherwise.
