From 706487807377ae276c3d0f45347b3702d791da12 Mon Sep 17 00:00:00 2001 From: Todor Tomov Date: Thu, 8 Feb 2018 04:41:59 -0500 Subject: [PATCH] media: ov5645: Fix write_reg return code I2C transfer functions return number of successful operations (on success). Do not return the received positive return code but instead return 0 on success. The users of write_reg function already use this logic.
