Even better, it also fixes this one:

drivers/mtd/chips/cfi_cmdset_0020.c: In function 'cfi_staa_write_buffers':
drivers/mtd/chips/cfi_cmdset_0020.c:651:1: error: the frame size of 1064 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]

I have not even looked what that is, I only saw show up the other day.
