Re: [PATCH 4.19 066/206] soundwire: slave: dont init debugfs on device registration error

Hi!

[ Upstream commit 8893ab5e8ee5d7c12e0fc1dca4a309475064473d ]

The error handling flow seems incorrect, there is no reason to try and add debugfs support if the device registration did not succeed. Return on error.

• return ret;
  

  }

return ret;

Mainline is significantly different here; this patch does not make sense in v4.19 -- as it does not do anything.

Best regards, Pavel
