From 2a0de2c84288fdf9381f6e2a85c0c6825221851e Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Wed, 12 Oct 2016 05:50:54 -0300 Subject: [PATCH] [media] DaVinci-VPFE-Capture: Delete an unnecessary variable initialisation in 11 functions The local variable "ret" will be set to an appropriate value a bit later. Thus omit the explicit initialisation at the beginning.
