commit 16c702ef3b9cff320c2adbfa853e00088adbf689
Author: Brian Paul <brianp@vmware.com>

    softpipe: fix softpipe_delete_fs_state() failed assertion
    
    The var!=softpipe->fs_variant assertion was failing because we weren't
    nulling the softpipe->fs_variant pointer when binding a new shader.
    Since softpipe->fs_variant depends on the current fs, it's of no use
    when a new FS is bound.
    
    Fixes http://bugs.freedesktop.org/show_bug.cgi?id=53318
    
    Note: This is a candidate for the 8.0 branch.
