From 216d526c89d144928f095f2800bc6c67e968d628 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sat, 14 Jan 2006 13:21:25 -0800 Subject: [PATCH] fbdev: Sanitize ->fb_mmap prototype No need for a file argument. If we'd really need it it's in vma->vm_file already. gbefb and sgivwfb used to set vma->vm_file to the file argument, but the kernel alrady did that.
