In the Linux kernel, the following vulnerability has been resolved:
fbdev: au1200fb: Fix a memory leak in au1200fbdrvprobe()
In au1200fbdrvprobe(), when platformgetirq fails(), it directly returns from the function with an error code, which causes a memory leak.
Replace it with a goto label to ensure proper cleanup.
