Hi,
"drivers/i2c/busses/i2c-nomadik.c" just got some loved, so I was
wondering if the below patch could be reviewed.
It does not apply anymore because of the recent change, but the
explanation in the commit message and the proposed change still make
sense to me.
If it looks valid, I could send a V2.
So any feedback would be appreciated.

Since commit a410963ba4c0 ("Merge branch 'i2c-embedded/for-next' of
git://git.pengutronix.de/git/wsa/linux"), there is no more
'request_mem_region()' call in this driver.
So remove the 'release_mem_region()' call from the remove function which is
likely a left over.
There is no details in the above commit log, but at its end we can read:
Conflicts:
drivers/i2c/busses/i2c-nomadik.c
This may explain why this call has been left here.

This patch is completely speculative and without details about commit
a410963ba4c0 it's hard to be sure of the intent.
All I can say is that it looks logical to me and that it compiles!
