Hi!

From: Xiaolei Wang <redacted>

commit cffa4b2122f5f3e53cf3d529bbc74651f95856d5 upstream.

After initializing the regmap through
syscon_regmap_lookup_by_compatible, then regmap_attach_dev to the
device, because the debugfs_name has been allocated, there is no
need to redistribute it again

? redistribute?

Anyway, this patch is clearly buggy:

 
 	if (!strcmp(name, "dummy")) {
-		kfree(map->debugfs_name);
+		if (!map->debugfs_name)
+			kfree(map->debugfs_name);
 

It runs kfree only if the variable is NULL. That's clearly useless,
kfree(NULL) is NOP, and this causes memory leak.

Best regards,
								Pavel
