Subject: [PATCH] IX2505V: i2c transfer error code ignored
Date: Sun, 7 Nov 2010 14:57:13 +0100	[thread overview]
Message-ID: <201011071457.14929.zzam@gentoo.org> (raw)

Hello Malcolm!

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).

The attached patch fixes this.

Regards
Matthias
