API non-compliance was located by coccinelle
This is mostly cosmetic since the returned value is only compared
at present, however if remaining time (completion occurred) where ever
used, then a signal received would be interpreted as a large remaining
jiffies left, which would be wrong.
Compile tested with: omap2plus_defconfig (implies CONFIG_FB_OMAP2_DSS)
Patch is against 4.7.0-rc7 (localversion-next -next-20160724)
