Summary
drm/msm/a6xx: Fix refcount leak in a6xx_gpu_init
Details

In the Linux kernel, the following vulnerability has been resolved:

drm/msm/a6xx: Fix refcount leak in a6xxgpuinit

ofparsephandle() returns a node pointer with refcount incremented, we should use ofnodeput() on it when not need anymore.

a6xxgmuinit() passes the node to offinddevicebynode() and ofdmaconfigure(), offinddevicebynode() will takes its reference, ofdmaconfigure() doesn't need the node after usage.

Add missing ofnodeput() to avoid refcount leak.
