From b0674e0675520beeca7a52ae7e610d751996e8ed Mon Sep 17 00:00:00 2001 From: =?utf8?q?J=C3=A9r=C3=B4me=20Pouiller?= Date: Wed, 15 Jan 2020 13:54:32 +0000 Subject: [PATCH] staging: wfx: simplify update of DTIM period MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Current code parse the TIM and retrieve the DTIM period. It is far easier to rely on bss_info_changed() for this job. It is no more necessary to run task asynchronously. So set_beacon_wakeup_period_work is now useless.
