From 0ee29814c6be17a924761d3712eb8ad63cfe13ac Mon Sep 17 00:00:00 2001 From: Roderick Colenbrander Date: Mon, 12 Dec 2022 20:49:35 -0800 Subject: [PATCH] HID: playstation: fix free of uninialized pointer for DS4 in Bluetooth. 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.")
