From 1784ea5527ed756f946958f45f74d1f15797c366 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Mon, 30 Mar 2009 01:04:44 +0200 Subject: v4l2: use old-style i2c API for kernels < 2.6.26 instead of < 2.6.22 From: Hans Verkuil Originally the intention was to switch to the new style i2c API starting with the introduction of the API in 2.6.22. However, the i2c_new_probed_device() function has a lethal bug that wasn't fixed until 2.6.25. Or more accurately, it was only fixed in the stable series of 2.6.25 and 2.6.26. Given the fact that the new i2c API also changed starting with 2.6.26 (the addition of i2c_device_id), it is easiest to switch APIs starting with 2.6.26. This patch updates all the legacy code accordingly.

Instead just pass the input, output and config (new!) arguments directly.
