[PATCH][next] regmap: fix return of unintialized value in variable ret

[Colin King]

From: Colin Ian King <colin.k...@canonical.com>

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")
Signed-off-by: Colin Ian King <colin.k...@canonical.com>
