From 1cba97d71dca1a3c22b4d7f97893249817036215 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Fri, 14 Sep 2007 05:13:54 -0300 Subject: [PATCH] V4L/DVB (6471): tuner: i2c_client cannot be part of the tuner struct The bus-based I2C subsystem allocates the i2c_client struct. So if in order to be able to convert the tuner to the bus-based I2C API the embedded i2c_client struct must be removed from the tuner struct and replaced with a pointer.
