[ Upstream commit 1d512ee861b80da63cbc501b973c53131aa22f29 ]
Many error paths in __regmap_init rely on ret being pre-initialised to
-EINVAL, add an extra initialisation in after the new call to
regmap_set_name.
Fixes: 94cc89eb8fa5 ("regmap: debugfs: Fix handling of name string for debugfs
init delays")
