[PATCH AUTOSEL 6.1 11/22] ASoC: SOF: topology: simplify code to prevent static analysis warnings

[Sasha Levin]

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

[ Upstream commit 55cb3dc271d81f1982c949a2ac483a6daf613b92 ]

make KCFLAGS='-fanalyzer' sound/soc/sof/intel/ reports a possible NULL
pointer dereference.

sound/soc/sof/topology.c:1136:21: error: dereference of NULL ‘w’
[CWE-476] [-Werror=analyzer-null-dereference]

 1136 |     strcmp(w->sname, rtd->dai_link->stream_name))

The code is rather confusing and can be simplified to make static
analysis happy. No functionality change.

[PATCH AUTOSEL 6.1 12/22] ASoC: Intel: sof_sdw: Update BT offload config for soundwire config

From: Uday M Bhat <uday.m.bhat@intel.com>

[ Upstream commit a14aded9299187bb17ef90700eb2cf1120ef5885 ]

For soundwire config, SSP1 is used for BT offload. This is enabled
in sof_sdw_quirk_table
