With “CONFIG_CROS_EC_DEBUGFS=y” it will not build as a module, it will be built in. I.e. Will not appear in lsmod.
In my .config, it appears as:
CONFIG_CROS_EC_DEBUGFS=m
But with =Y is might still work.
Try the ec-syslog again.
What does the output of “lsmod |grep -i cros” give? Something like this:
leds_cros_ec 12288 0
led_class_multicolor 16384 1 leds_cros_ec
gpio_cros_ec 12288 0
cros_ec_chardev 12288 0
cros_ec_hwmon 12288 0
cros_ec_debugfs 16384 0
cros_ec_sysfs 12288 0
cros_ec_dev 12288 0
cros_ec_lpcs 20480 0
cros_ec 20480 1 cros_ec_lpcs
