From c7a45e5b4f8c2f96cd242ae1b1c06e7fb19a08d0 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Tue, 5 Mar 2013 06:55:26 -0300 Subject: [PATCH] [media] em28xx: Prepare to support 2 different I2C buses Newer em28xx devices have 2 buses. Change the logic to allow using both buses. This patch was generated by this small script: for i in drivers/media/usb/em28xx/*.c; do sed 's,->i2c_adap,->i2c_adap[dev->def_i2c_bus],g;s,->i2c_client,->i2c_client[dev->def_i2c_bus],' done Of course, em28xx.h needed manual edit.
