Subject: [PATCH for 2.6.28] NAND: fsl_upm: fix build problem with 2.6.28-rc2

From: Wolfgang Grandegger <wg@...ndegger.com>

The patch fixes following build error:

  CC      drivers/mtd/nand/fsl_upm.o
drivers/mtd/nand/fsl_upm.c: In function 'fun_chip_init':
drivers/mtd/nand/fsl_upm.c:168: warning: passing argument 2 of 'of_mtd_parse_partitions' from incompatible pointer type
drivers/mtd/nand/fsl_upm.c:168: warning: passing argument 3 of 'of_mtd_parse_partitions' from incompatible pointer type
drivers/mtd/nand/fsl_upm.c:168: error: too many arguments to function 'of_mtd_parse_partitions'
make[1]: *** [drivers/mtd/nand/fsl_upm.o] Error 1

The breakage was introduced in 69fd3a8d098faf41a04930afa83757c0555ee360
("[MTD] remove unused mtd parameter in of_mtd_parse_partitions()").

While at it, also add a check for the of_mtd_parse_partitions() return
value.
