This is a note to let you know that I've just added the patch titled
usb: host: fix incorrect updating of offset
to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-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.
If you have any questions about this process, please let me know.

The variable temp is incorrectly being updated, instead it should be offset otherwise the loop just reads the same capability value and loops forever. Thanks to Alan Stern for pointing out the correct fix to my original fix. Fix also cleans up clang warning:
drivers/usb/host/ehci-dbg.c:840:4: warning: Value stored to 'temp' is never read
