Subject: dmaengine: pl330: Remove unused mc_len field from _pl330_req struct
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=be025329fd4223f3442fffc35f8255bd64d0d526;p=linux-beck.git

dmaengine: pl330: Remove unused mc_len field from _pl330_req struct

The mc_len is initialized but its value is never read again, so remove it.
