This is a note to let you know that I've just added the patch titled
counter: 104-quad-8: Fix Synapse action reported for Index signals
to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-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.

Signal 16 and higher represent the device's Index lines. The priv->preset_enable array holds the device configuration for these Index lines. The preset_enable configuration is active low on the device, so invert the conditional check in quad8_action_read() to properly handle the logical state of preset_enable.
