Subject: [PATCH] HID: thrustmaster: fix memory leak in thrustmaster_interrupts()
Date: Thu, 27 Mar 2025 23:11:46 +0000 [thread overview]
Message-ID: <20250327231146.6388-1-qasdev00@gmail.com> (raw)
In thrustmaster_interrupts(), the allocated send_buf is not
freed if the usb_check_int_endpoints() check fails, leading
to a memory leak.
Fix this by ensuring send_buf is freed before returning in
the error path.
Fixes: 50420d7c79c3 ("HID: hid-thrustmaster: Fix warning in thrustmaster_probe by adding endpoint check")
