5 mtd: ixp4xx: oops in ixp4xx_flash_probe
6
7 In commit "c797533 mtd: abstract last MTD partition parser argument" the
8 third argument of "mtd_device_parse_register()" changed from start address
9 of the MTD device to a pointer to a struct.
10
11 The "ixp4xx_flash_probe()" function was not converted properly, causing
12 an oops during boot.
13
14 This patch fixes the problem by filling the needed information into a
15 "struct mtd_part_parser_data" and passing it to
16 "mtd_device_parse_register()".
