Ivan Bornyakov b2d1956547 bus: imx-weim: fix branch condition evaluates to a garbage value
[ 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.
