From: Samuel Thibault Date: Sun, 1 Nov 2020 18:39:13 +0000 (+0100) Subject: speakup_dummy: log about characters received by the dummy driver X-Git-Tag: v5.11-rc1~164^2~107 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a79db45fa54e2420c9fe977a6a5835c466888b5a;p=thirdparty%2Fkernel%2Flinux.git speakup_dummy: log about characters received by the dummy driver The dummy speakup driver is used to check that speakup is working properly, without the need for actually owning the hardware. Some drivers require receiving characters, so we need a way to check that this is working properly.
