Subject: drm/i915: Make intel_ring_setup_status_page() static
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=af75f2691870c575030bbd42adf17457afbe7242;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/i915: Make intel_ring_setup_status_page() static

This function is only used in intel_ringbuffer.c, so restrict it to that
file. The function was moved around to avoid a forward declaration and
group it with its user.
