From 00f4bc5184c19cb33f468f1ea409d70d19f8f502 Mon Sep 17 00:00:00 2001 From: William Breathitt Gray william.gray@linaro.org Date: Thu, 16 Mar 2023 16:34:26 -0400 Subject: [PATCH] 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.
