From d457bff2763366513bce36c2fc51fcba12a2f912 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Thu, 1 Jun 2023 10:25:55 +0200 Subject: [PATCH] wifi: ath10k: Convert to platform remove callback returning void MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. 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.
