From c91ba8c8514307c3c60dc2b1015d379b1d01c809 Mon Sep 17 00:00:00 2001 From: =?utf8?q?J=C3=A9r=C3=B4me=20Pouiller?= Date: Tue, 17 Dec 2019 16:15:19 +0000 Subject: [PATCH] staging: wfx: simplify wfx_conf_tx() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Error management of wfx_conf_tx() can be simplified. In add, the hardware command "hif_set_edca_queue_params" never returns any error.
