From a3b7b227f1250a90c8a9542ea6398a61e1708174 Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Tue, 29 Sep 2020 22:25:43 +0200 Subject: [PATCH] net: rtlwifi: Remove void* casts related to delayed work INIT_DELAYED_WORK() takes two arguments: A pointer to the delayed work and a function reference for the callback. The rtl code casts all function references to (void *) because the callbacks in use are not matching the required function signature. That's error prone and bad pratice. Some of the callback functions are also global, but only used in a single file. Clean the mess up by: - Adding the proper arguments to the callback functions and using them in the container_of() constructs correctly which removes the hideous container_of_dwork_rtl() macro as well. - Removing the type cast at the initializers - Making the unnecessary global functions static Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: Thomas Gleixner Acked-by: Kalle Valo Signed-off-by: David S.
