Well, I managed a minimal change to prevent the infinite loop I was seeing from 
happening.  (I’ll overhaul the bvm2835 i2c driver some other time.)

So, my i2c configuration changes now seem to work correctly on my test platform 
(Raspberry Pi B+ v1.2, with 2 i2c devices — a DS3231 RTC and a TSL2561 Lux 
sensor).  I have an i2c PWM controller that I’ll be adding soon, but I don’t 
expect any problems.

If there aren’t any objections, I’ll go ahead and check this stuff in 
(including a back-out of the kernel config file changes that pinned the i2c 
device pspecs).
