    [PATCH] remove non-cleanroom pwc driver compression · 88c18346
    Alan Cox authored
    The original pwc author raised some questions about the reverse
    engineering of the decompressor algorithms used in the pwc driver.
    Having done some detailed investigation it appears those concerns that
    clean room policy was not followed are reasonable.  I've also had a
    friendly discussion with Philips to ask their view on this.
    
    This removes the problem items of code which reduces the pwc
    functionality in the kernel a little but leaves all the framework for
    setup that will be needed for decompressors in user space (where they
    eventually belong).  This change set is designed to be the minimal risk
    change set given that 2.6.12 is hopefully close to hand, with a view to
    merging the much updated pwc code in 2.6.13 series kernels.
    
    Someone else can then redo the decompressors properly (clean room) in
    user space.
    
    Note that while its easy to say that it should have been caught earlier,
    but the violation was really only obvious to someone who had access to
    both the proprietary source and the 'GPL' source.
