From 0f3b48385213355a2d4408bec1b481ffcf0e8638 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Tue, 1 May 2007 23:26:31 +0200 Subject: [PATCH] i2c-algo-bit: Add i2c_bit_add_numbered_bus Add i2c_bit_add_numbered_bus(), which is equivalent to i2c_bit_add_bus except that it calls i2c_add_numbered_adapter() at the end instead of i2c_add_adapter().
