 * This method searches for the mute LED GPIO configuration
 * provided as OEM string in SMBIOS. The format of that string
 * is HP_Mute_LED_P_G or HP_Mute_LED_P
 * where P can be 0 or 1 and defines mute LED GPIO control state (low/high)
 * that corresponds to the NOT muted state of the master volume
 * and G is the index of the GPIO to use as the mute LED control (0..9)
 * If _G portion is missing it is assigned based on the codec ID
 *
 * So, HP B-series like systems may have HP_Mute_LED_0 (current models)
 * or  HP_Mute_LED_0_3 (future models) OEM SMBIOS strings
 *
 *
 * The dv-series laptops don't seem to have the HP_Mute_LED* strings in
 * SMBIOS - at least the ones I have seen do not have them - which include
 * my own system (HP Pavilion dv6-1110ax) and my cousin's
 * HP Pavilion dv9500t CTO.
 * Need more information on whether it is true across the entire series.
