From af504e5d39de35dc3de5f42c357fe1b519fea33f Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Wed, 2 Nov 2011 12:54:03 +0100 Subject: [PATCH] ARM: OMAP: I2C: Fix omap_register_i2c_bus() return value on success Commit 4d17aeb1c5b2375769446d13012a98e6d265ec13 ("OMAP: I2C: split device registration and convert OMAP2+ to omap_device") makes omap2_i2c_add_bus() return a pointer to an omap_device instead on success instead of 0. This breaks the omap_register_i2c_bus() ABI and results in the igep0020 board code detecting an I2C bus registration error when there is none. Fix the problem by using PTR_RET() instead of PTR_ERR() in omap2_i2c_add_bus().
