mtd: lantiq-flash: drop iounmap for devm_ allocated data
Data allocated with devm_ioremap or devm_ioremap_nocache should not be freed using iounmap, because doing so causes a dangling pointer, and a subsequent double free. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ expression x; @@ ( x = devm_ioremap(...) | x = devm_ioremap_nocache(...) ) @@ expression r.x; @@ * iounmap(x) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@intel.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
