Subject: [085/272] [media] IX2505V: i2c transfer error code ignored

2.6.37-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Matthias Schwarzott <zzam@...too.org>

commit 13d28e4917fb6cf6898e8998f01ab83b3f468aeb upstream.

It seems that ix2505v driver ignores a i2c error in ix2505v_read_status_reg.
This looks like a typing error using (ret = 1) instead of correct (ret == 1).
