However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Both ath10k platform drivers return zero unconditionally in their remove callback, so they can be trivially converted to use .remove_new(). Also fix on of the more offending whitespace issues in the definition of ath10k_snoc_driver.
