24 | /* NOTE: the full version of this header is in the v4l-dvb repository | ||
25 | * and allows v4l i2c drivers to be compiled on pre-2.6.26 kernels. | ||
26 | * The version of this header as it appears in the kernel is a stripped | ||
27 | * version (without all the backwards compatibility stuff) and so it | ||
28 | * looks a bit odd. | ||
29 | * | ||
30 | * If you look at the full version then you will understand the reason | ||
31 | * for introducing this header since you really don't want to have all | ||
32 | * the tricky backwards compatibility code in each and every i2c driver. | ||
33 | * | ||
34 | * If the i2c driver will never be compiled for pre-2.6.26 kernels, then | ||
35 | * DO NOT USE this header! Just write it as a regular i2c driver. | ||
