interesting.  we have a weird problem to deal with then,
and i'm not sure of the solution.  (it's related to having
two files with the same case-insensitive name.)

try installing this file, without the patch:

   https://www.netbsd.org/~mrg/kaveri_mec2.bin

which is the expected file.  you can find *all* these files
in the linux-firmware package from kernel.org, if there are
other files that are missing..
