[PATCH] video: fbdev: intelfb: intelfb_i2c.c: Cleaning up variable that is never used

From: Rickard Strandqvist <redacted>

Variable ar assigned a value that is never used.
I have also removed all the code that thereby serves no purpose.

This was found using a static code analysis program called cppcheck

Are you sure this is the right fix?

Do we need to read the register in case we don't care about return
value?
