From 660ec7cfdf0b48c135ada6cd67af25d66404d3ba Mon Sep 17 00:00:00 2001 From: Edward O'Callaghan Date: Wed, 14 Jan 2015 02:14:21 +1100 Subject: drivers/i2c/w83795: Fix tautology from wrong return type The correct type-signature of 'do_smbus_write_byte' is: int do_smbus_write_byte(u32 smbus_io_base, u32 device, u32 address, u8 val) and so storing the return type in a 'u32' is inappropriate, leading to a tautological compare of 'ret < 0' and 'err < 0'.
