Q6 based WiFi fw loading is supported across
different targets, ex: IPQ8074/QCS404. In order to
support different fw names/pas id etc, populate
hardcoded param using driver data.

The patch title suggests a core remoteproc change, but the change is
platform-specific. Can you fix up the title accordingly?

You can still use the macro as is even in the new data structure.

You may want to check for NULL firmware name as well before invoking
rproc_alloc.

Why is your compatible changing?

This patch prepares the driver for the introduction of some variation of
some of the given parameters. Please submit this patch together with the
patch introducing that new code.

You lost qcom, in the compatible here.
