Subject: dm ioctl: remove double parentheses
X-Git-Tag: v4.12-rc1~120^2~25

dm ioctl: remove double parentheses

The extra pair of parantheses is not needed and causes clang to generate
warnings about the DM_DEV_CREATE_CMD comparison in validate_params().

Also remove another double parentheses that doesn't cause a warning.
