From 0ac62eb4b78df85291e73ab367ebba0e27cb7d76 Mon Sep 17 00:00:00 2001 From: Siarhei Vishniakou Date: Wed, 18 May 2022 09:42:52 -0700 Subject: Do not load keylayout if required kernel module is missing Some key layouts require the presence of a specific kernel module. If the kernel module is not present, the layout should not be loaded. In this CL, we add an option to specify which kernel modules / configs are needed inside the kl file.
