  SubGraph and Module Instance ids take 32 bits, so use idr_alloc_u32
instead of idr_alloc to able to accomdate valid ranges.

typo: accommodate.

Also worth checking https://www.kernel.org/doc/html/latest/core-api/idr.html
"The IDR interface is deprecated; please use the XArray instead."

Thanks for this hit, this looks really good and specially lookups 
without Locking, this could cleanup the code a bit.

Having said that I would still like this patch go as it is with idr for 
now, and I can plan to rework on converting idr to xa later, as there 
are few more Qcom Audio drivers that have usage of idr.

thanks,
srini
