to handle this with a quirk. Some drivers have an option to disable use
of MSI. While this is a convenient workaround for the driver author,

+This practice is particularly helpful if you maintain a stable branch and
want at the same time to credit the author, track changes, merge the fix,
and protect the submitter from complaints. Note that under no circumstances
can you change the author's identity (the From header), as it is the one
which appears in the changelog.

+Special note to back-porters: It seems to be a common and useful practice
to insert an indication of the origin of a patch at the top of the commit
message (just after the subject line) to facilitate tracking. For instance,
here's what we see in 2.6-stable :
if (strlen(device) <= 5 || strncmp(device, "/dev/", 5) != 0)
return -EINVAL;
strncpy(devname, device + 5, sizeof(devname) - 1);

a new LSM is accepted into the kernel when its intent (a description of
what it tries to protect against and in what cases one would expect to
use it) has been appropriately documented in Documentation/security/.
