Message:

Change max buffer size for i2cproc_bus_read() from 4000 to 4096.

This is the /proc/bus/i2c-x handler. Don't know why there is
a limit at all but my kernel 2.4.18 calls this with a size of 4096,
2.4.17 was usually 1024. Couldn't find any program in lm_sensors
that actually used this file, though.
