Sure it's common.  But no one has mentioned that it really needs the
NO_SYNC_CACHE quirk.  So unless I hear otherwise, I will assume it doesn't
need the quirk and it will continue to work fine.

The problem is that a lot of these quirks were added with no documentation
and a cut/paste of both NO_6_BYTE and NO_SYNCHRONIZE_CACHE quirks even
though only one of them was needed.  Now that no USB devices should
receive a 6 byte command, that only leaves the NO_SYNCHRONIZE_CACHE
quirks.  I am temporarily disabling them to flush out which ones are
REALLY needed.  They have been disabled since 2003/07/29 and 2003/08/07
for -current and -stable, respectively.  I have had 0 messages saying that
anything was broken by this.
