[RESEND PATCH 2/7] i2c: i2c-cros-ec-tunnel: Set retries to 3

2014-08-20 Thread Javier Martinez Canillas 
From: Derek Basehore 

Since the i2c bus can get wedged on the EC sometimes, set the number of retries
to 3. Since we un-wedge the bus immediately after the wedge happens, this is the
correct fix since only one transfer will fail.

Yes, if possible I prefer if all the series are picked by Lee Jones to avoid any
dependencies.

I think a define for this is overkill, yet I don't really mind.

I assume this goes via MFD, let me know if I should take it.
