Subject: [PATCH v2 63/65] staging: wfx: simplify wfx_tx_queue_get_num_queued()
Date: Wed, 15 Jan 2020 13:55:35 +0000
Message-ID: <20200115135338.14374-64-Jerome.Pouiller@silabs.com> (raw)
In-Reply-To: <20200115135338.14374-1-Jerome.Pouiller@silabs.com>

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

wfx_tx_queue_get_num_queued() can take advantage of BIT() instead of
maintaining one variable for a counter and another for a mask.

In add, wfx_tx_queue_get_num_queued() has no real reason to return a
size_t instead of an int.
