Description
A vulnerability in the Linux kernel's perf subsystem for ARM NI was fixed by adding a missing platform_set_drvdata() call in the arm_ni_probe() function. Without this fix, platform_get_drvdata() called during device removal would return NULL, potentially causing improper cleanup or instability.
