Hello,
While looking at the 5.9 kernel config I noticed there is no easy way to
disable LED support in general.
There's this NEW_LEDS thing that is not shown, etc.
So I get:
# make oldconfig
scripts/kconfig/conf --oldconfig Kconfig
*
* Restart config...
*
*
* LED Support
*
LED Support (NEW_LEDS) [Y/?] (NEW) y
LED Class Support (LEDS_CLASS) [M/y/?] (NEW) n
CONFIG_LEDS_CLASS:
This option enables the LED sysfs class in /sys/class/leds. You'll
need this to do anything useful with LEDs. If unsure, say N.

And there is no 'n' option. None of the devices as dependencies (on the
left) are enabled.
SND_HDA_GENERIC_LEDS is automagically enabled and disabling it via vi is
no option.
So how do I disable this stuff?
Kind regards,
Udo
