Subject: mtd: pxa3xx_nand: fix a memory leak
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=1a3591920e5100ba112a19e10a09ce7a5da1ab23;p=deliverable%2Flinux.git

mtd: pxa3xx_nand: fix a memory leak

In pxa3xx_nand_remove, we should call nand_release instead of
mtd_device_unregister to properly free bad block table memory
and bad block descriptor memory.
