From 11b3c20bdd15d17382068be569740de1dccb173d Mon Sep 17 00:00:00 2001 From: Gabriel Krisman Bertazi Date: Fri, 6 Jan 2017 15:57:31 -0200 Subject: drm: Change the return type of the unload hook to void MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The integer returned by the unload hook is ignored by the drm core, so let's make it void. This patch was created using the following Coccinelle semantic script (except for the declaration and comment in drm_drv.h): Compile-tested only. // @ get_name @ struct drm_driver drv; identifier fn; @@ drv.unload = fn; @ replace_type @ identifier get_name.fn; @@ - int + void fn (...) { ... } @ remove_return_param @ identifier get_name.fn; @@ void fn (...) { <... if (...) return - ... ; ...> } @ drop_final_return @ identifier get_name.fn; @@ void fn (...) { ... - return 0; } // Suggested-by: Daniel Vetter Signed-off-by: Gabriel Krisman Bertazi Acked-by: Christian König .
