Subject: [PATCH] staging: pi433: Fix rf69_set_tx_cfg() logic
Date: Wed, 27 Mar 2019 08:11:20 +0000	[thread overview]
Message-ID: <20190327081120.11152-1-realwakka@gmail.com> (raw)

Moved code to configure sync to where check enable_sync option before.
There is no need to check enable_sync twice. Configuring sync should be
executed immediately after enabling sync.
