From 517b358fddd737e81a3e0762d0893722871fafe9 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?J=C3=A9r=C3=B4me=20Pouiller?= Date: Wed, 1 Apr 2020 13:03:44 +0200 Subject: staging: wfx: simplify wfx_tx_queue_mask_get() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit It is far simpler to return a pointer instead of an error. Thus, it is no more necessary to pass a pointer reference as argument.
