[PATCH v2 1/5] drm/i915/guc: Expose (intel)_lr_context_size()

[yu.dai@intel.com]

From: Dave Gordon <david.s.gordon@intel.com>

The GuC code needs to know the size of a logical context, so we
expose get_lr_context_size(), renaming it intel_lr_context__size()
to fit the naming conventions for nonstatic functions.
