[David Binderman <dcb314@xxxxxxxxxxx>]

Hello there,

Source code is

        if ((temp & PIPEACONF_PIPE_STATE) == 1)
            break;

but

$ fgrep PIPEACONF_PIPE_STATE `find drivers/gpu/drm/gma500 -name \*.h -print`
drivers/gpu/drm/gma500/psb_intel_reg.h:#define PIPEACONF_PIPE_STATE		(1 << 30)
$ 

Suggest new code

        if ((temp & PIPEACONF_PIPE_STATE) != 0)
            break;

Regards

David Binderman
