Subject: [PATCH v4 1/8] dmaengine: xilinx: xdma: Get rid of unused code
Date:   Fri,  8 Dec 2023 14:49:22 +0100
Message-Id: <20231208134929.49523-2-jankul@alatek.krakow.pl>

Get rid of duplicated macro definitions, as these macros are defined
earlier in the file. Also, get rid of unused member
of 'struct xdma_desc'.
