Yes, we would like a little background, e.g., a URL for a bug report
if it exists, a description of how a user might recognize this
problem, etc.  See https://git.kernel.org/linus/1b30dfd376e2 ("PCI:
Mark Broadcom HT1100 and HT2000 Root Port Extended Tags as broken")
for a sample.

Also update the subject line to use the same pattern as 1b30dfd376e2.
