From: Govind Singh <govinds@codeaurora.org>

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.

This tag is not really useful and doesn't follow the style of having
your email prefix the text. I'd expect to see

[gokulsri@codeaurora.org: made some sort of change]

Same question, why not unsigned?
