Multiple drivers using regmap can probe in parallel, leading to
concurrent calls to regmap_debugfs_init() with name=NULL and dev=NULL.
The dummy_index is a global static variable inside regmap-debugfs.c,
not something the callers have knowledge of or control over. Using IDA
is the appropriate fix for this internal concurrency issue.

Apologies for missing the Signed-off-by line. Added in v2.
