[PATCH 4.9 014/102] dm ioctl: remove double parentheses
From: Greg Kroah-Hartman
Date: Fri Apr 06 2018 - 10:50:58 EST
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Matthias Kaehlcke <mka@xxxxxxxxxxxx>
commit e36215d87f301f9567c8c99fd34e6c3521a94ddf upstream.
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.
