From e99eac5e4ea3bd8671bb1cedad10c3fec90ec0de Mon Sep 17 00:00:00 2001 From: Seth Forshee Date: Fri, 17 Aug 2012 11:17:02 -0500 Subject: vga_switcheroo: Don't require handler init callback This callback is a no-op in nouveau, and the upcoming apple-gmux switcheroo support won't require it either. Rather than forcing drivers to stub it out, just make it optional and remove the callback from nouveau.
