[PATCH] nand: mrvl: use ERR_CAST() for returning error pointers

[PATCH] nand: mrvl: use ERR_CAST() for returning error pointers

[Sascha Hauer]

ERR_CAST exists to return error pointers as error pointers without
casting them explicitly to the correct pointer type.

Also this Fixes:
In function 'alloc_nand_resource':
warning: return makes pointer from integer without a cast
