i2c: Remove NOP i2c_algorithm.algo_control() methods
David Brownell [Sat, 13 Oct 2007 21:56:32 +0000 (23:56 +0200)]
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.
