[SRU][O][PATCH 1/1] mtd: rawnand: fix double free in atmel_pmecc_create_user()

[Massimiliano Pellizzer]

From: Dan Carpenter <dan.carpenter at linaro.org>

The "user" pointer was converted from being allocated with kzalloc() to
being allocated by devm_kzalloc().  Calling kfree(user) will lead to a
double free.
