Chris Wilson 09b1a4e4b5 drm/i915/lrc: Clear context restore/save inhibit flags for new contexts ... CTX_CONTEXT_CONTROL (CTX_SR_CTL) operates as a masked register and so will only apply the bits that are selected by the upper half. In the case of selectively enabling sr inhibit, this may mean the context keeps the current setting (so forgetting to save the context later, eventually leading to a very upset GPU!).
