From 3fc6b6671559d947f3f9a6d8829d3481a17934f4 Mon Sep 17 00:00:00 2001 From: Ryan Mallon Date: Sat, 28 Jan 2012 08:51:40 +1100 Subject: [PATCH] vmwgfx: Fix assignment in vmw_framebuffer_create_handle commit bf9c05d5b6d19b3e4c9fe21047694e94f48db89b upstream. The assignment of handle in vmw_framebuffer_create_handle doesn't actually do anything useful and is incorrectly assigning an integer value to a pointer argument. It appears that this is a typo and should be dereferencing handle rather than assigning to it directly. This fixes a bug where an undefined handle value is potentially returned to user-space.
