Subject: [PATCH 1/7] remoteproc: qcom: pas: Fixup the elf class for SM8450 remoteprocs

From: Yogesh Lal <quic_ylal@...cinc.com>

The coredumps for the ADSP,CDSP and MPSS subsystems will be 64 bit from
SM8450 SoCs onward. Update the elf class as elf64 accordingly.

Fixes: 5cef9b48458d ("remoteproc: qcom: pas: Add SM8450 remoteproc support")
