[PATCH 4.2 177/258] mtd: nand: sunxi: fix sunxi_nand_chips_cleanup()

From: Greg Kroah-Hartman
Date: Sat Oct 17 2015 - 22:49:41 EST


4.2-stable review patch. If anyone has any objections, please let me know.

------------------

From: Boris BREZILLON <boris.brezillon@xxxxxxxxxxxxxxxxxx>

commit 8e375ccda31ccc73b087134e263c48d2114534f4 upstream.

The sunxi_nand_chips_cleanup() function is missing a call to list_del()
which generates a double free error.
