[ Upstream commit e41a962f82e7afb5b1ee644f48ad0b3aee656268 ]
There is a upstream commit cffa4b2122f5("regmap:debugfs:
Fix a memory leak when calling regmap_attach_dev") that
adds a if condition when create name for debugfs_name.
With below function invoking logical, debugfs_name is
freed in regmap_debugfs_exit(), but it is not created again
because of the if condition introduced by above commit.
regmap_reinit_cache()
regmap_debugfs_exit()
...
regmap_debugfs_init()
So, set debugfs_name to NULL after it is freed.
Fixes: cffa4b2122f5 ("regmap: debugfs: Fix a memory leak when calling regmap_attach_dev")
