[i2c] [PATCH] i2c: improve lost-arbitration handling in i2c-algo-pcf

[Daniel Smolik]

 >Attached is a patch that improves multi-master support for PCF8584.
 >The current implementation of multi-master support (mine) in
 >i2c-algo-pcf does not properly handle a collision detected during 
 >wait_for_bb()
 >and thus causes an error that is only recoverable by reloading the
 >relevant device drivers.  I'd appreciate your consideration of this
 >patch.

 >The only affected driver is i2c-envctrl.c-- currently out-of-kernel,
 >in development; you
 >can find it here if you are interested:

 >This change has been tested by a few individuals (on Sun Microsystems
 >E250 servers) over the course of several months, and rectifies
 >occasional errors seen without the patch applied.

 >I'll be happy to provide further clarification if you are interested.
