From c3ffe0ca4a75ec1b5183e6141bed4dfcde4309fb Mon Sep 17 00:00:00 2001 From: Tobias Klauser Date: Mon, 10 Aug 2015 12:26:32 +0200 Subject: [PATCH] net: eth: altera: Remove sgdmadesclen member from altera_tse_private altera_tse_private->sgdmadesclen is always assigned assigned the same value and never changes during runtime. Remove the struct member and use a new define for sizeof(struct sgdma_descrip) instead. Signed-off-by: Tobias Klauser Signed-off-by: David S.
