Use the define and delete the comment.
write_reg(par, MIPI_DCS_ENTER_INVERT_MODE);

Enable inversion mode
What the heck is an inversion mode and why would you want it?

Should I name it:
Enable MIPI_DCS_ENTER_INVERT_MODE

What I'm saying is the changelog should explain why would want to apply the patch. What does the inversion mode do? Is it inverting the color or flipping something upside down?
Probably if I had a background in graphics I would know what "Enable inversion mode" means... But three words is not a proper and complete commit message normally.
