commit 651e4769ba2a9f20c4b8a823ae2727bf7fa9c9f0 upstream.

In chasing down issues with EDID probing, I found some
duplicated but incomplete logic used to power the chip on and
off.

This patch refactors the adv7511_power_on/off functions, so
they can be used for internal needs.

Why are you asking for these 3 patches to be backported to the 4.9
stable tree?  What bugs are they fixing?  How do they meet the stable
kernel rules?

totally confused,

greg k-h

This patch is re-writes the i2c address to ADV7511_REG_EDID_I2C_ADDR register to ensure its properly set before reading the EDID data.
In the past, the backporting is for Kernel v4.4 and you asked to port for 4.9 also.
