This is a note to let you know that I've just added the patch titled
staging: vt6656: fix sign of rx_dbm to bb_pre_ed_rssi.
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.
If you have any questions about this process, please let me know.

bb_pre_ed_rssi is an u8 rx_dm always returns negative signed values add minus operator to always yield positive.
fixes issue where rx sensitivity is always set to maximum because the unsigned numbers were always greater then 100.
