Custom kernel configuration for sound

[ctor]

Sound does not work in the release of Tiny Core 64 pure version 15 on my computer because the configuration doesn't support my sound hardware. I am not asking to change Tiny Core -- instead, i am working on a custom kernel configuration. My hardware:

Code: [Select]

sudo lspci -vv
00:0e.0 Multimedia audio controller: Intel Corporation Celeron N3350/Pentium N4200/Atom E3900 Series Audio Cluster (rev 0b)
        DeviceName: Onboard - Sound
        Subsystem: Device 1c6c:122a
I get this error (and others -- only interested in this one):

Code: [Select]

i2c_hid: Unknown symbol drm_panel_remove_follower
I believe this can be solved by enabling the "Device Tree and Open Firmware support" setting in the Linux configuration menu (make menuconfig).
Before I go down the rabbit hole, is there a reason that Tiny Core developers do not set this?
