The STAC9708/11 AC97 codecs implement the PCM Out Path & Mute bit in the General Purpose register (0x20:F), even though they don't implement the actual function in the mixer. Since the alsa tests for the function by toggling the bit and reading it back to see if it changed, it mistakenly creates a useless control. This patch explicitly removes the control when the codec is an STAC9708/11. I put the check in patch_sigmatel_stac9708_specific(), because I have an SBLive with this chip on it. I don't know if the STAC9758 or other codecs also behave this way. If they do, then this check could maybe go in patch_sigmatel_stac97xx_specific(), or some other more general function.
