[PATCH] drm/i915: Remove redundant check for negative timeout while doing an atomic pipe update

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Just a minor knit. Stumbled across the kernel doc for schedule_timeout() which
quotes "In all cases the return value is guaranteed to be non-negative". Also,
the return code of schedule_timeout() already checks for negative values
"return timeout < 0 ? 0 : timeout;" and returns 0 in such cases. So,
let's do away with the redundant check for an atomic pipe update.
