Subject: ASoC: SOF: Validate and correct the core id against the number of cores of the DSP
X-Git-Url: http://git.ipfire.org/gitweb/index.cgi?a=commitdiff_plain;h=d9265a36f4be6f322814e0eb255e4e29b39dd5cc;p=thirdparty%2Fkernel%2Flinux.git

ASoC: SOF: Validate and correct the core id against the number of cores of the DSP

Generic development topologies can reference core id outside of the range
of the number of DSP cores the device might have.
Product families have different number of cores, for example:
Intel TGL has 4, TGL-H has 2, ADL has 4, ADL-S has 2, etc
The development topologies are tuned for the higher end devices and in this
case they will fail on DSP with less number of cores.

Override the out of range core id from topology to primary core and inform
the user about it.
