From: Ivan Bornyakov <i.bornyakov@xxxxxxxxxxx> [ Upstream commit 1adab2922c58e7ff4fa9f0b43695079402cce876 ] If bus type is other than imx50_weim_devtype and have no child devices, variable 'ret' in function weim_parse_dt() will not be initialized, but will be used as branch condition and return value. Fix this by initializing 'ret' with 0. This was discovered with help of clang-analyzer, but the situation is quite possible in real life.
