[Intel-gfx] [PATCH 08/41] drm/i915: Remove superfluous wait_for_error() from throttle-ioctl

2016-10-20 Thread Chris Wilson
The throttle-ioctl never touches the struct_mutex. It does, however, as part of its ABI report whether the hardware is terminally wedged. For that purposes, it only has to report the current state and not incur the cost of checking/waiting every invocation, as we do not have to wait for a reset
