From 3f03dade77f39b299e4b12dafd58329e22023afd Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Mon, 4 Mar 2024 20:08:29 +0200 Subject: misc: hisi_hikey_usb: Remove unused of_gpio.h of_gpio.h is deprecated and subject to remove. The driver doesn't use it, simply remove the unused header.

However the value returned is ignored (apart from emitting a warning) 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. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.
