powerpc/spufs: Check file offset before calculating write size in fixed-sized files Based on an original patch from Roel Kluin <roel.kluin@gmail.com>. The write size calculated during regs and fpcr writes may currently go negative. Because size is unsigned, this will wrap, and our check for EFBIG will fail. Instead, do the check for EFBIG before subtracting from size. Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
