Re: [PATCH V3 1/2] i2c-designware: Add i2c bus locking support

[David E. Box]

Hi,

Expect something tonight should the latest tests run okay. I needed to include
an EPROBE_DEFER to address the unavailibity of the pci driver needed in order to
request the lock during probe of the i2c device. This due to the lock now being
requested during probe because of the hang.
