Subject: [AVR32] Implement dma_mapping_error()
X-Git-Tag: v4.13~40237^2~63^2~9
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=6eb484fe92e2f67f888dc87e97bfd938c0f7404e;p=mirror_ubuntu-bionic-kernel.git

[AVR32] Implement dma_mapping_error()

dma_map_single() never fails, so dma_mapping_error() simply returns 0.
