  • drm/i915: restore backlight precision when converting from ACPI
  • ALSA: hda - Add new GPU codec ID to snd-hda
  • clk: bcm281xx: don't use unnamed structs or unions

  • target: Allow non-supporting backends to set pi_prot_type to 0
  • target: Don't allow setting WC emulation if device doesn't support
  • x86, mm, hugetlb: Add missing TLB page invalidation for hugetlb_cow()
  • powerpc: irq work racing with timer interrupt can result in
  • timer interrupt hang
  • [media] rtl28xxu: do not hard depend on staging SDR module
  • [media] rtl28xxu: silence error log about disabled rtl2832_sdr module
