From f368ed6088ae9c1fbe1c897bb5f215ce5e63fa1e Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Thu, 30 Jul 2015 15:59:57 -0700 Subject: char: make misc_deregister a void function With well over 200+ users of this api, there are a mere 12 users that actually checked the return value of this function. And all of them really didn't do anything with that information as the system or module was shutting down no matter what. So stop pretending like it matters, and just return void from misc_deregister(). If something goes wrong in the call, you will get a WARNING splat in the syslog so you know how to fix up your driver. Other than that, there's nothing that can go wrong. Cc: Alasdair Kergon Cc: Neil Brown Cc: Oleg Drokin Cc: Andreas Dilger Cc: "Michael S.
