Subject: [PATCH v2 1/2] staging: rtl8192u: remove unnecessary function implementation
Date: Mon, 31 Oct 2022 23:25:39 +0530	[thread overview]
Message-ID: <6f5a4313fc21365bf733c25385aef79554ffb253.1667237959.git.drv@mailo.com> (raw)
In-Reply-To: <cover.1667237959.git.drv@mailo.com>

This driver is a single standalone driver and does not have any loading
dependencies on another associated drivers. The build results in one
single .ko object. The current implementation of the function
ieee80211_tkip_null simply returns back to the caller without any useful
instruction executions. It does not lead to auto-loading of any other
associated modules as the initial design implementation appears to be.

Hence the call to ieee80211_tkip_null() and its implementation is
unnecessary and should be removed.
