When reduced version firmware files were added (matching major
component being the only strict requirement), the minor version was
still tracked and a notification reported if it was older. However,
the patch version should really be tracked as well for the same
reasons. The KMD can work without the change but if the effort has
been taken to release a new firmware with the change then there must
be a valid reason for doing so - important bug fix, security fix, etc.
And in that case it would be good to alert the user if they are
missing out on that new fix.

AFAICS in linux-firmware we don't have any 70.5.4 binaries, the newest
ones are 70.5.1.

Some of the info here is redundant from print_fw_ver(). Can we have a
single print with all the info we need?
Something like:
GuC firmware i915/mtl_guc_70.bin (v70.6.5, expected v70.6.4 or newer)
Otherwise, I'd suggest demoting this to gt_dbg to avoid printing the
same thing twice at info verbosity
