Subject: crypto: marvell/cesa - const-ify argument to mv_cesa_get_op_cfg()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c439e4eec73373c6d5b7129ece69d67978ada307;p=linux-beck.git

crypto: marvell/cesa - const-ify argument to mv_cesa_get_op_cfg()

mv_cesa_get_op_cfg() does not write to its argument, it only reads.
So, let's make it const.
