From deb00d2785bedd379caa7aaf18c1ffb824580b9d Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Tue, 28 May 2019 11:02:49 +0200 Subject: fbdev: make unregister/unlink functions not fail MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Except for driver bugs (which we'll catch with a WARN_ON) this is only to report failures of the new driver taking over the console. There's nothing the outgoing driver can do about that, and no one ever bothered to actually look at these return values. So remove them all. v2: fixup unregister_framebuffer in savagefb, fbtft, ivtvfb, and neofb drivers, reported by kbuild.
