The CONFIG_IPC_CLASSES option has been introduced in a patchset adding
Intel Thread Director support. Unfortunately, this patchset had to be
removed due to complications (see issues #1084 and #1120), which was
done in commits b6c8d6ad35 ("Update v6.2 patches") and a53f55d8f0
("Update v6.1 patches"). Those commits accidentally left the now unused
CONFIG_IPC_CLASSES option in place, so remove it now.
Changes:
- Big IPTS/ITHC update:
- Update IPTS driver to its latest version. This switches the
interface from a custom device interface to hidraw.
- Include ITHC driver to support touchscreen and pen on newer
generation devices.
Note: Both require an updated IPTSd version.
- Rebase onto 6.1.9
