[PATCH RESEND v5 01/24] dmaengine: Fix dma_slave_config.dst_addr description

From: Serge Semin
Date: Mon Aug 22 2022 - 14:54:44 EST


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.
