Hi Ricardo,

Thanks for the review.

There's actually a compiler warning on this, too. I'll reword this being:

Fix a compiler warning about an uninitialised err_msg variable by printing
the error where it is handled:

drivers/platform/x86/intel/int3472/discrete.c:440:24: warning: ‘err_msg’ may be used uninitialized [-Wmaybe-uninitialized]
  440 |                 return dev_err_probe(int3472->dev, ret, err_msg);

Fixes: 5de691bffe57 ("platform/x86: Add intel_skl_int3472 driver")
Cc: stable

It seems it's always been there but I think it's a false positive: the
compiler probably just can't figure out err_msg is unused if ret is
non-zero.
