Subject: [PATCH 08/19] staging: wfx: split out wfx_tx_fill_rates() from wfx_tx_confirm_cb()
Date: Fri, 15 May 2020 10:33:14 +0200	[thread overview]
Message-ID: <20200515083325.378539-9-Jerome.Pouiller@silabs.com> (raw)
In-Reply-To: <20200515083325.378539-1-Jerome.Pouiller@silabs.com>

From: Jérôme Pouiller <jerome.pouiller@silabs.com>

wfx_tx_confirm_cb() is a big function. A big part of its body aims to
fill the rates list. So, create a new function wfx_tx_fill_rates() and
make wfx_tx_confirm_cb() smaller.
