[PATCH 1/1] HID: playstation: fix free of uninialized pointer for DS4 in Bluetooth.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The 'buf' variable is only used in the USB (if-path) and not in the Bluetooth
else-path. Since it is not set to NULL. this results in freeing an uninitialized
pointer. Since the else code-path doesn't need buf, just return 0.

Fixes: 2d77474a2392 ("HID: playstation: add DualShock4 bluetooth support.")
