Sinan Kaya b5b809532e dmaengine: qcom_hidma: remove useless debugfs file removal 
Since 'commit acc29fb8f7 ("debugfs: ->d_parent is never NULL or
negative")', HIDMA object removal is no longer working. This is due to
redundant debugfs remove call in hidma_debug_uninit.

debugfs_remove_recursive(dmadev->debugfs);
debugfs_remove_recursive(dmadev->stats);

The first remove is for the directory. Second remove is for the file under
the directory. The directory remove makes file remove invalid.

Unable to handle kernel NULL pointer dereference at virtual address
