From d2cc2f0b35465951eaaf0387fd55e29835ed7ea6 Mon Sep 17 00:00:00 2001 From: Laura Abbott Date: Mon, 5 Oct 2015 19:33:29 -0300 Subject: [media] si2157: return -EINVAL if firmware blob is too big A previous patch added a check if the firmware is too big, but it didn't set the return error code with the right value. [mchehab@osg.samsung.com: I ended by applying a v1 of Laura's patch, without the proper return code.
