Subject: [PATCH v4 01/24] dmaengine: Fix dma_slave_config.dst_addr description
Date: Thu, 28 Jul 2022 17:28:18 +0300	[thread overview]
Message-ID: <20220728142841.12305-2-Sergey.Semin@baikalelectronics.ru> (raw)
In-Reply-To: <20220728142841.12305-1-Sergey.Semin@baikalelectronics.ru>

Most likely due to a copy-paste mistake the dst_addr member of the
dma_slave_config structure has been marked as ignored if the !source!
address belong to the memory. That is relevant to the src_addr field of
the structure while the dst_addr field as containing a destination device
address is supposed to be ignored if the destination is the CPU memory.
Let's fix the field description accordingly.
