Argh. The patch is corrupted:
patching file drivers/mtd/ubi/cdev.c
patch: **** malformed patch at line 11: struct file *file,
Could you please glance at Documentation/SubmittingPatches in the
kernel tree? Could you please re-send the series properly? Or send
me the patches as an attachment. Thanks.
