From 6da629c85871a0cb65fad3e0c0a440d64002b0a7 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Thu, 14 Jan 2021 18:57:17 +0100 Subject: [PATCH] tty: vcc: Drop unnecessary if block MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit If vcc_probe() succeeded dev_set_drvdata() is called with a non-NULL value, and if vcc_probe() failed vcc_remove() isn't called. So there is no way dev_get_drvdata() can return NULL in vcc_remove() and the check can just go away.
