Bug#926057: linux: please include intel-lpss-pci.ko in some udeb

[Cyril Brulebois <kibi@debian.org>]

Source: linux
Version: 4.19.28-2
Severity: normal
Tags: d-i

(debian-boot@ and olasd@ in copy.)

Hi,

Nicolas Dandrimont was brave enough to try and help out with d-i by
testing the latest development version on his laptop. We discovered some
shim bug (for this specific laptop), but also noticed missing support
for his touchpad & trackpad (IDs will be provided in a follow-up mail).

Comparing with the list of modules obtained on an installed system, we
first tried to ship d-i with these:

  /lib/modules/4.19.0-4-amd64/kernel/drivers/platform/x86/intel-hid.ko
  /lib/modules/4.19.0-4-amd64/kernel/drivers/input/sparse-keymap.ko (dependency of the former)

but there were no changes (looking at /proc/bus/input/devices). Adding
those made both touchpad & trackpad pop up (and be usable):

  /lib/modules/4.19.0-4-amd64/kernel/drivers/mfd/intel-lpss.ko (dependency of the latter)
  /lib/modules/4.19.0-4-amd64/kernel/drivers/mfd/intel-lpss-pci.ko

Since I suppose there might be other peripheral types using this (like
wireless?), I'm not sure this should belong to input-modules, even if
that's the udeb we double-checked first.


Thanks to Mozilla for hosting the BSP!
