Big thank you for your nice cleanups and reworks, I will follow those in 
the future :-)

I take the opportunity to thank you also for the merge of the 2 otm8009a 
patches.

Moreover, if you think I need to update otm8009a driver with the same 
reworks (include order, DRM_ERROR_RATELIMITED, error msg, remove msg if 
successfull, struct data alignment...), please tell me :)
Note: I plan to update it soon with new backlight_enable/disable api...

Thank you again,
Philippe :-)
