In the Linux kernel, the following vulnerability has been resolved:
drm: xlnx: zynqmpdpsub: Add NULL check in zynqmpaudio_init
devmkasprintf() calls can return null pointers on failure. But some return values were not checked in zynqmpaudio_init().
Add NULL check in zynqmpaudioinit(), avoid referencing null pointers in the subsequent code.
