I am using the CVS of both i2c and lm_sensors.  I did a `cvs update` 
before applying each of the i2c and lm_sensors patches.  So, in theory, I 
should have the latest version of both.

My i2c.h has NO evidence of a function called i2c_delay().  That would 
explain the error.

Could you tell me how you generated this patch?  Was it using the 
mkpatch.pl script together with another (maybe more than one) script(s)?  
The reason that I'm asking is that I'd like to do this myself for any 
kernel.  If I use your patches, I'd have to be using 2.4.21 or 2.4.22.
