Yes, indeed I noticed the same but did not investigate further. Please, also add: Cc: <stable@vger.kernel.org> # v3.6+ Andi

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.
