[PATCH 1/6] ASoC: Intel: Skylake: Use correct function to access iomem space

[Amadeusz Sławiński]

From: Amadeusz Sławiński <amadeuszx.slawinski@intel.com>

For copying from __iomem, we should use __ioread32_copy.

[PATCH 2/6] ASoC: Intel: Fix use of potentially uninitialized variable

[Amadeusz Sławiński]

From: Amadeusz Sławiński <amadeuszx.slawinski@intel.com>

If ipc->ops.reply_msg_match is NULL, we may end up using uninitialized
mask value.

reported by smatch:
sound/soc/intel/common/sst-ipc.c:266 sst_ipc_reply_find_msg() error: uninitialized symbol 'mask'.

Please see linux/limits.h and check if this can't be replaced by an 
equivalent found there.

[PATCH 3/6] ASoC: dapm: Expose snd_soc_dapm_new_control_unlocked properly

[Amadeusz Sławiński]

From: Amadeusz Sławiński <amadeuszx.slawinski@intel.com>

We use snd_soc_dapm_new_control_unlocked for topology and have local
declaration, instead declare it properly in header like already declared
snd_soc_dapm_new_control.

[PATCH 4/6] ASoC: Intel: Skylake: Print module type instead of id

[Amadeusz Sławiński]

From: Amadeusz Sławiński <amadeuszx.slawinski@intel.com>

When we are printing module params, we were actually printing module id
instead of type, but debug message was saying that number we get is type.
So print module type, as it is useful when debugging paths, but also
keep printing module id, as it is used in all other logs.

[PATCH 5/6] ASoC: Intel: Skylake: Release topology when we are done with it

[Amadeusz Sławiński]

Currently topology is kept in memory while driver is running. It's
unnecessary, as it's only needed during parsing.

[PATCH 6/6] ASoC: Intel: NHLT: Fix debug print format

[Amadeusz Sławiński]

From: Amadeusz Sławiński <amadeuszx.slawinski@intel.com>

oem_table_id is 8 chars long, so we need to limit it, otherwise it
may print some unprintable characters into dmesg.
