Subject: [PATCH] dmaengine: stm32-mdma: Remove redundant initialization of pointer hwdesc
Date:   Sat,  4 Dec 2021 14:00:32 +0000
Message-Id: <20211204140032.548066-1-colin.i.king@gmail.com>

Precedence: bulk

The pointer hwdesc is being initialized with a value that is never
read, it is being updated later in a for-loop. The assignment is
redundant and can be removed.
