While text /before/ is indeed called a "prefix", text /after/ is not a "postfix",
but a "suffix".

The device tree is supposed to describe hardware.

The name of which file to load can hardly be considered part of the HW.

Possible solutions:
1) derive the file name from the compatible string
2) pass the name as a module parameter
3) something else

If one provides the entire suffix, including the underscore, then you can
simplify the code:

	snprintf(config.fwname, sizeof(config.fwname), "qca/nvm_%08x%s.bin", soc_ver, suffix ? suffix : "");
