The ISA msnd drivers have loops fetching the ring-buffer head, tail
and size values inside the loops.  Such codes are inefficient and
fragile.

This patch optimizes it, and also adds the sanity check to avoid the
endless loops.

On this Lenovo machine, there are two front mics, and both of them are
assigned the same name "Mic", but pulseaudio can't support two mics
with the same name, as a workaround, we change the location for one of
them, then the driver will assign "Front Mic" and "Mic" for them.

The commit dba9b7b6 ("ALSA: hda - Fix doubly initialization of
i915 component") contained a typo that leads to the unbalance of i915
module reference.  The value to be checked is not chip->driver_type
but chip->driver_caps.

ASoC: Updates for v4.13

The big news with this release is the of-graph card, this provides a
replacement for simple-card that is much more flexibile and scalable,
allowing many more systems to use a generic sound card than was possible
before:

 - The of-graph card, finally merged after a long and dedicated effort
   by Morimoto-san.
 - New widget types intended mainly for use with DSPs.
 - New drivers for Allwinner V3s SoCs, Ensonic ES8316, several classes
   of x86 machine, Rockchip PDM controllers, STM32 I2S and S/PDIF
   controllers and ZTE AUD96P22 CODECs.

For driver debugfs, debugfs_remove_recursive() is called which is not
needed as it is already done in ASoC core debugfs. And a device managed
memory need not be freed explicitly as device core frees it up. So
remove unnecessary skl_debugfs_exit().

Commit bdd0384a ("ASoC: Intel: Skylake: Add support to read firmware
registers") introduced firmware register read so added sst-dsp-priv.h but
missed adding sst-dsp.h as that leads to below compiler warning:

Pull MIPS fixes from Ralf Baechle:
 "Here's a final round of fixes for 4.12:

   - Fix misordered instructions in assembly code making kenel startup
     via UHB unreliable.

   - Fix special case of MADDF and MADDF emulation.

   - Fix alignment issue in address calculation in pm-cps on 64 bit.

   - Fix IRQ tracing & lockdep when rescheduling

   - Systems with MAARs require post-DMA cache flushes.

  The reordering fix and the MADDF/MSUBF fix have sat in linux-next for
  a number of days. The others haven't propagated from my pull tree to
  linux-next yet but all have survived manual testing and Imagination's
  automated test system and there are no pending bug reports"
