Subject: [PATCH] can: avoid double unlikely() notation when using IS_ERR()
Date:   Thu, 10 Dec 2020 09:53:21 +0100
Message-Id: <20201210085321.18693-1-a@unstable.cc>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

The definition of IS_ERR() already applies the unlikely() notation
when checking the error status of the passed pointer. For this
reason there is no need to have the same notation outside of
IS_ERR() itself.

Clean up code by removing redundant notation.
