Subject: [PATCH] i2c: busses: i2c-nomadik: Remove a useless call in the remove function

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.

Fixes: a410963ba4c0 ("Merge branch 'i2c-embedded/for-next' of git://git.pengutronix.de/git/wsa/linux
Signed-off-by: Christophe JAILLET <christophe.jaillet@...adoo.fr>

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!
