patch "counter:ti-eqep: remove floor" added to staging-linus
This is a note to let you know that I've just added the patch titled
counter:ti-eqep: remove floor
to my staging git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
in the staging-linus branch.
The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.

Subject: counter:ti-eqep: remove floor
The hardware doesn't support this. QPOSINIT is an initialization value that is triggered by other things. When the counter overflows, it always wraps around to zero.
