drm/syncobj: Avoid kmalloc(GFP_KERNEL) under spinlock
drivers/gpu/drm/drm_syncobj.c:202:4-14: ERROR: function drm_syncobj_find_signal_pt_for_point called on line 390 inside lock on line 389 but uses GFP_KERNEL
Find functions that refer to GFP_KERNEL but are called with locks held.
Generated by: scripts/coccinelle/locks/call_kern.cocci
v2:
syncobj->timeline still needs protect.
v3:
use a global signaled fence instead of re-allocation.
v4:
Don't need moving lock.
Don't expose func.
v5:
rename func and directly return.
Tested by: syncobj_wait and ./deqp-vk -n dEQP-VK.*semaphore* with
lock debug kernel options enabled.
