Subject: [PATCH v2] i2c: busses: i2c-nomadik: Remove a useless call in the remove function
Date:   Fri, 30 Jun 2023 23:23:28 +0200
Message-Id: <62ae6810d41e0429ebaadfac8a95409f4bc72456.1688160163.git.christophe.jaillet@wanadoo.fr>

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.

v2: synch with latest -next

v1: https://lore.kernel.org/all/4f4c2c5c20b61c4bb28cb3e9ab4640534dd2adec.1629530169.git.christophe.jaillet@wanadoo.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!
