As noted by Hans, we currently fail to generate uevents for ACPI serdev controller as they do not have any ACPI companions from which ACPI modaliases are constructed.
In fact, we should not have been generating modaliases for controllers in the first place as controllers are not bound to drivers. This series applies on top of Hans's minimal fix which suppresses the uevent errors for ACPI controllers (even though it could replace it entirely if preferred). Johan v2 - add the missing static keyword for the modalias attribute when moving the definition (noted by Greg) Johan Hovold (2): serdev: do not generate modaliases for controllers serdev: only match serdev devices drivers/tty/serdev/core.c | 80 +++++++++++++++++++++++++---------------------- 1 file changed, 42 insertions(+), 38 deletions(-) -- 2.15.1
