Subject: [media] USB: as102_usb_drv.c: Remove useless return variables Author: Peter Senna Tschudin <[email protected]> Date: Tue May 20 07:33:46 2014 -0300 This patch remove variables that are initialized with a constant, are never updated, and are only used as parameter of return. Return the constant instead of using a variable. Verified by compilation only.
