Hi,

There appears to be a bug in kernel where after a probe deferral by the 
drm driver, the deferred drm function is never called again at a later 
point.

I have a iMX6 based board where there is pca9547 i2c mux between the 
display and the mx6 processor. The drm driver tries to get EDID 
information but the I2C mux pca9547 driver is not yet called, so drm 
driver does a probe deferral as expected. However the drm function is 
never called again after the pca9547 driver completes initialization 
because of which the display remains blank. Things used to work with 
next-20151202 and I saw it stop working sometime around next-20151223 
onwards.

If I comment the "ddc-i2c-bus" entry in device tree, then the display 
works in next-20160128 since the probe deferral does not happen.

Has anyone else seen this issue?

Logs provided below.

Thanks,
Akshay
