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