counter: 104-quad-8: Fix Synapse action reported for Index signals
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. Fixes: f1d8a071d45b ("counter: 104-quad-8: Add Generic Counter interface support") Cc: <stable@vger.kernel.org> Link: https://lore.kernel.org/r/20230316203426.224745-1-william.gray@linaro.org/ Signed-off-by: William Breathitt Gray <william.gray@linaro.org>
