Subject: constify quirks table
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=59a708ba74246218e566235c0a5a9cbc8e1138ec;p=openbsd

constify quirks table

Not that big now, but quirks are likely to grow in the feature and there is
no reason to keep them writable.

OK and tested by mglocker
