PATCH 1/1 scx200_hrt - fix precedence bug manifesting as 27x clock in 1 MHz mode

Fix paren-placement / precedence bug breaking initialization for 1 MHz clock mode. Also fixes comment spelling error, and fence-post (off-by-one) error on symbol used in request_region.

this patch fixes http://bugzilla.kernel.org/show_bug.cgi?id=7242
but I cannot close it, so I'll leave it to those so empowered.

should be ok for -stable, if the spelling correction doesnt break the rules. The fence-post error is real, just not caught on x86, AFAICT.

Thanks [email protected], [email protected], for the reports and patch test, and [email protected] for the independent patch and verification.
