Subject: [media] si2157: return -EINVAL if firmware blob is too big

From: Laura Abbott <labbott@fedoraproject.org>

commit d2cc2f0b35465951eaaf0387fd55e29835ed7ea6 upstream.

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. This patch contains the difference between v2 and v1 of
 the Laura's "si2157: Bounds check firmware" patch]
