While disabling ConfigFS Android gadget, android_disconnect() calls kill_all_hid_devices(), if CONFIG_USB_CONFIGFS_F_ACC is enabled, to free the registered HIDs without checking whether the USB accessory device really exist or not. If USB accessory device doesn't exist then we run into following kernel panic: ----8<---- [ 136.724761] Unable to handle kernel NULL pointer dereference at virtual address 00000064 [ 136.724809] pgd = c0204000 [ 136.731924] [00000064] *pgd=00000000 [ 136.737830] Internal error: Oops: 5 [#1] SMP ARM [ 136.738108] CPU: 0 PID: 0 Comm: swapper/0 Not tainted 3.18.0-rc4-00400-gf75300e-dirty #76 [ 136.742788] task: c0fb19d8 ti: c0fa4000 task.ti: c0fa4000 [ 136.750890] PC is at _raw_spin_lock_irqsave+0x24/0x60 [ 136.756246] LR is at kill_all_hid_devices+0x24/0x114 ---->8---- This patch adds a test to check if USB Accessory device exists before freeing HIDs.
