Subject: [PATCH v1] misc: fastrpc: Create fastrpc scalar with correct buffer count
Date:   Wed, 14 Jun 2023 17:24:45 +0530

A process can spawn a PD on DSP with some attributes that can be
associated with the PD during spawn and run. The invocation
corresponding to the create request with attributes has total
4 buffers at the DSP side implementation. If this number is not
correct, the invocation is expected to fail on DSP. Added change
to use correct number of buffer count for creating fastrpc scalar.
