Title:
  Bluetooth does not work but WiFi does on Intel 7265 with both Ubuntu
  16.04 and 16.10

Status in linux-firmware package in Ubuntu:
  Confirmed

Bug description:
  On an Acer V3-574-7481 with built-in stock Intel 7265 wireless
  hardware, WiFi works perfectly but Bluetooth does not. The System
  Settings applet reports "No Bluetooth adapters found" and the option
  to enable Bluetooth is grayed out. However, Bluetooth hardware is
  reported by "dmesg" and a firmware patch file is applied automatically
  during boot.

  *Bluetooth works on this same machine booted into Windows 10.* The
  machine is dual-boot from separate partitions.
