Subject: [lm-sensors] [PATCH] hwmon: (atxp1) Fix device detection logic
Date: Sun, 29 Jun 2008 10:31:11 +0000	[thread overview]
Message-ID: <20080629123111.26ffc368@hyperion.delvare> (raw)

The atxp1 device detection code has a major logic flaw, fix it. Not
sure how we managed to miss this when the driver was merged...

Sebastian, can you please review and test this patch? I've tested with
i2c-stub but an additional test with a real device can't hurt.
