Fix paren-placement / precedence bug breaking initialization for 1 MHz clock mode. Also fix comment spelling error, and fence-post (off-by-one) error on symbol used in request_region. Addresses http://bugzilla.kernel.org/show_bug.cgi?id=7242 Thanks alexander.krause@erazor-zone.de, dzpost@dedekind.net, for the reports and patch test, and phelps@mantara.com for the independent patch and verification.
