From 778bfc74f3b523b91853b6c7cc5b4b01527ab713 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Sun, 14 Jun 2009 12:12:11 +0200 Subject: v4l2-i2c-drv.h: add comment describing when not to use this header. From: Hans Verkuil Make it very clear that this header should not be used for i2c drivers that do not need to be compiled for pre-2.6.26 kernels. As soon as the minimum supported kernel in the v4l-dvb repository becomes 2.6.26 or up, then this header should be removed entirely.
