From 564d21054d1f61d9448a93b3fa8a254a29713d26 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Tue, 25 Nov 2008 09:07:00 -0200 Subject: fix boards for kernels with algo_control From: Mauro Carvalho Chehab changeset 4ecae6da8244 removed algo_control from i2c drivers. However, on older kernels, a dummy function to implement algo_control is required, otherwise, an OOPS is generated. This patch adds a backport for all i2c drivers that defines an i2c_algorithm, except for cafe_ccic, since OLPC hardware only works for kernels newer than 2.6.19. Some of the backported drivers would need also extra changes to work with older kernels, as specified on v4l/versions.txt. Yet, I decided to add the backport for those drivers also, since the lack of algo_control doesn't generate any compilation error, but it is enough to break the driver. So, better to all for all boards than to allow compiling a kernel backported that just generates OOPS.
