From 0a9c14751377a1407f5e35791e13651d2fc7801c Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Sat, 13 Mar 2010 20:56:56 +0100 Subject: i2c-algo-bit: Add pre- and post-xfer hooks Drivers might have to do random things before and/or after I2C transfers. Add hooks to the i2c-algo-bit implementation to let them do so.
