From d7a3a6801913a4b57a7e525c4906d348213acfb0 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Thu, 22 Jul 2021 13:51:40 +0200 Subject: [PATCH] ASoC: cx20442: tty_ldisc_ops::write_wakeup is optional TTY layer does nothing if tty_ldisc_ops::write_wakeup is NULL, so there is no need to implement an empty one in cx20442. Drop it.
