From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
A recent commit removed the intialization of ret and now the !config
error return path returns a bogus uninitialized value in ret. Fix
this by explicitly setting ret to -EINVAL for this error exit path.
Addresses-Coverity: ("Uninitialized scalar value")
Fixes: 94cc89eb8fa5 ("regmap: debugfs: Fix handling of name string for debugfs init delays")
