Subject: [PATCH 5.4 078/155] Input: fix stale timestamp on key autorepeat events

From: Dmitry Torokhov <dmitry.torokhov@...il.com>

commit 4134252ab7e2c339a54302b88496cb5a89cdbaec upstream.

We need to refresh timestamp when emitting key autorepeat events, otherwise
they will carry timestamp of the original key press event.

Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=206929
Fixes: 3b51c44bd693 ("Input: allow drivers specify timestamp for input events")
