From c81109332068b44db4fd7b650c0e6bc0fc1411f1 Mon Sep 17 00:00:00 2001 From: Tushar Behera Date: Mon, 19 Nov 2012 16:31:42 +0530 Subject: i2c: core: Remove definition of i2c_smbus_process_call i2c_smbus_process_call has no users in the kernel, so this can be removed. Documentation for the same has been updated accordingly. Fixes following sparse warning. drivers/i2c/i2c-core.c:1871:5: warning: symbol 'i2c_smbus_process_call' was not declared. Should it be static?
