Look in that directory, and you will likely see no .h files in that
diretory. This is where the error is reported. No match to *.h in that
dir and no dir to search recursively has a .h extention. :-)
Instead try:
# grep pci_dev */*/*.h
or
# grep pci_dev */*.h
And see if you get no error.
Then try
# grep pci_dev *.h
and you should see the error again
An alternate?
find . -name \*.h -print0 | xargs -0 grep "pci_dev"

"best" is a subjective term. I bet everyone here has their own best, and
some probably have other ways to do the above.
