Roy Spliet dedaa8f0e6 drm/nvc0/fb: take lock in nvc0_ram_put()
Kernel panic caused by list corruption in ltcg seems to indicate a
concurrency issue.

Take mutex of pfb like nv50_ram_put() to eliminate concurrency.

V2: Separate critical section into separate function, avoid taking the
    lock twice on NVC0
