From 3be27d37c257fa5f99363f9c8e06e405cbad712e Mon Sep 17 00:00:00 2001 From: David Brownell Date: Sat, 13 Oct 2007 23:56:32 +0200 Subject: [PATCH] i2c: Remove NOP i2c_algorithm.algo_control() methods This removes NOP implementations of i2c_algorithm.algo_control. With this change, there are no implementations of this hook in the kernel.org tree ... that hook seems about ripe to remove.
