ASoC: Fixes for v4.11
A few last minute fixes for v4.11, the STI fix is relatively large but
driver specific and has been cooking in -next for a little while now:
- A fix from Takashi for some suspend/resume related crashes in the
Intel drivers.
- A fix from Mousumi Jana for issues with incorrectly created
enumeration controls generated from topology files which could cause
problems for userspace.
- Fixes from Arnaud Pouliquen for some crashes due to races with the
interrupt handler in the STI driver.

The error handling in bxt_sst_dsp_init() got changed in a way that
it now derefences an uninitialized pointer when printing a warning
about the device not being found:
sound/soc/intel/skylake/bxt-sst.c: In function 'bxt_sst_dsp_init':
sound/soc/intel/skylake/bxt-sst.c:567:14: error: 'skl' may be used uninitialized in this function [-Werror=maybe-uninitialized]
As we do have a valid device pointer available at the call site,
let's use that instead.

Designware PCM is an extension to Designware I2S and they are dependent
on each other. For this reason, make Designware PCM a boolean which will
compile with Desigwnare I2S module. The name of the module is not changed
but the name of the files need to be changed.
Also, without this commit we get errors when probbing designware_i2s module
because of unspecified license:
designware_pcm: module license 'unspecified' taints kernel.

base firmware library manifest is loaded using load library IPC. This is

'asoc/fix/sti' into asoc-linus
|
|
The FE setups of Intel SST bytcr_rt5640 and bytcr_rt5651 drivers carry
the ignore_suspend flag, and this prevents the suspend/resume working
properly while the stream is running, since SST core code has the
check of the running streams and returns -EBUSY. Drop these
superfluous flags for fixing the behavior.
Also, the bytcr_rt5640 driver lacks of nonatomic flag in some FE
definitions, which leads to the kernel Oops at suspend/resume like:
BUG: scheduling while atomic: systemd-sleep/3144/0x00000003

The bytcr-rt5640 driver has a few quirk setups depending on the board,
where the quirk value is set by DMI matching. When you have a new
device to add the support, you often experience to try the different
quirk by trial-and-error. Or, you may have a development model that
still has no proper DMI string. In either case, you'd need to compile
the driver at each time.
This patch introduces a module option to override the quirk value on
the fly. User can boot like snd-soc-sst-bytcr-rt5640.quirk=0x4004 to
override the default value without recompilation. It's a raw value,
so user needs to check the source code for the meaning of each bit.

Since recently UCM can pick up a configuration specific to the board
via card longname field, and we introduced a helper function
snd_soc_set_dmi_name() for that. So far, it was used only in one
place (sound/soc/intel/boards/broadwell.c), but it should be more
widely applied.
This patch puts a big hammer for that: it lets snd_soc_register_card()
calling snd_soc_set_dmi_name() unconditionally, so that all x86
devices get the better longname string. This would have no impact for
other systems without DMI support, as snd_soc_set_dmi_name() is no-op
on them.

Currently the following variables are global:
- card_priv, sample_rate and sample_format
,which is not a good idea as it prevents the usage of multiple
instances.
Make sample_rate and sample_format part of the imx_priv structure
and allocate imx_priv via the standard devm_kzalloc() mechanism
inside the probe function.

Reducing real_num_tx_queues needs to be in sync with skb queue_mapping
otherwise skbs with queue_mapping greater than real_num_tx_queues
can be sent to the underlying driver and can result in kernel panic.
One such event is running netconsole and enabling VF on the same
device. Or running netconsole and changing number of tx queues via
ethtool on same device.

Andrey Konovalov reported a BUG caused by the ip6mr code which is caused
because we call unregister_netdevice_many for a device that is already
being destroyed. In IPv4's ipmr that has been resolved by two commits
long time ago by introducing the "notify" parameter to the delete
function and avoiding the unregister when called from a notifier, so
let's do the same for ip6mr.
