From 93d783bcca69bfacc8dc739d8a050498402587b5 Mon Sep 17 00:00:00 2001 From: Curt Brune Date: Thu, 8 Aug 2013 12:11:03 -0700 Subject: [PATCH] hwmon: (adt7470) Fix incorrect return code check In adt7470_write_word_data(), which writes two bytes using i2c_smbus_write_byte_data(), the return codes are incorrectly AND-ed together when they should be OR-ed together. The return code of i2c_smbus_write_byte_data() is zero for success. The upshot is only the first byte was ever written to the hardware. The 2nd byte was never written out. I noticed that trying to set the fan speed limits was not working correctly on my system. Setting the fan speed limits is the only code that uses adt7470_write_word_data(). After making the change the limit settings work and the alarms work also. Signed-off-by: Curt Brune Cc: stable@vger.kernel.org Signed-off-by: Guenter Roeck --- Reading git-format-patch failed
