Title
wifi: rt2x00: Fix memory leak when handling surveys
Summary
In the Linux kernel, the following vulnerability has been resolved: wifi: rt2x00: Fix memory leak when handling surveys When removing a rt2x00 device, its associated channel surveys are not freed, causing a memory leak observable with kmemleak: unreferenced object 0xffff9620f0881a00 (size 512): comm "systemd-udevd", pid 2290, jiffies 4294906974 (age 33.768s) hex dump (first 32 bytes): 70 44 12 00 00 00 00 00 92 8a 00 00 00 00 00 00 pD.............. 00 00 00 00 00 00 00 00 ab 87 01 00 00 00 00 00 ................ backtrace: [<ffffffffb0ed858b>] __kmalloc+0x4b/0x130 [<ffffffffc1b0f29b>] rt2800_probe_hw+0xc2b/0x1380 [rt2800lib] [<ffffffffc1a9496e>] rt2800usb_probe_hw+0xe/0x60 [rt2800usb] [<ffffffffc1ae491a>] rt2x00lib_probe_dev+0x21a/0x7d0 [rt2x00lib] [<ffffffffc1b3b83e>] rt2x00usb_probe+0x1be/0x980 [rt2x00usb] [<ffffffffc05981e2>] usb_probe_interface+0xe2/0x310 [usbcore] [<ffffffffb13be2d5>] really_probe+0x1a5/0x410 [<ffffffffb13be5c8>] __driver_probe_device+0x78/0x180 [<ffffffffb13be6fe>] driver_probe_device+0x1e/0x90 [<ffffffffb13be972>] __driver_attach+0xd2/0x1c0 [<ffffffffb13bbc57>] bus_for_each_dev+0x77/0xd0 [<ffffffffb13bd2a2>] bus_add_driver+0x112/0x210 [<ffffffffb13bfc6c>] driver_register+0x5c/0x120 [<ffffffffc0596ae8>] usb_register_driver+0x88/0x150 [usbcore] [<ffffffffb0c011c4>] do_one_initcall+0x44/0x220 [<ffffffffb0d6134c>] do_init_module+0x4c/0x220 Fix this by freeing the channel surveys on device removal.
