As per information from Qualcomm [1], this property is not really supported beyond msm8916 (HFI V1) and some newer HFI versions really dislike receiving it, going as far as crashing the device. Only consider toggling it (via the module option) on HFIV1. While at it, get rid of the global static variable (which defaulted to zero) which was never explicitly assigned to for V1. Note: [1] is a reply to the actual message in question, as lore did not properly receive some of the emails..
