Subject: [PATCH v3 22/41] net: mac802154: Rename the main tx_work struct
Date: Mon, 17 Jan 2022 12:54:21 +0100 [thread overview]
Message-ID: <20220117115440.60296-23-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20220117115440.60296-1-miquel.raynal@bootlin.com>
This entry is dedicated to synchronous transmissions done by drivers
without async hook. Make this clearer that this is not a work that any
driver can use by at least prefixing it with "sync_". While at it, let's
enhance the comment explaining why we choose one or the other.
