Currently the variable ret is uninitialized and is only set if
the pointer alt_path is non-null. Fix this by ininitializing ret
to zero.
Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: 5ff013914c62 ("brcmfmac: firmware: Allow per-board firmware binaries")

I assume this will be fixed by Linus' patch "brcmfmac: firmware: Fix
firmware loading" and I should drop Colin's patch, correct?

That would be my assumption as well, but not sure when he will submit
another revision of it. You probably know what to do ;-)

I'd prefer my patch to be dropped in preference to Linus' fix.
