commit b0791dda813c179e539b0fc1ecd3f5f30f2571e2 upstream. BIOS on some HP laptops don't set the speaker-pins as fixed but expose as jacks, and this confuses the driver as if these pins are jack-detectable. As a result, the machine doesn't get sounds from speakers because the driver prepares the power-map update via jack unsol events which never come up in reality. The bug was introduced in some time in 3.2 for enabling the power-mapping feature. This patch fixes the problem by replacing the check of the persistent power-map bits with a proper is_jack_detectable() call.
