Summary
In the Linux kernel, the following vulnerability has been resolved: HID: nintendo: avoid bluetooth suspend/resume stalls Ensure we don't stall or panic the kernel when using bluetooth-connected controllers. This was reported as an issue on android devices using kernel 6.6 due to the resume hook which had been added for usb joycons. First, set a new state value to JOYCON_CTLR_STATE_SUSPENDED in a newly-added nintendo_hid_suspend. This makes sure we will not stall out the kernel waiting for input reports during led classdev suspend. The stalls could happen if connectivity is unreliable or lost to the controller prior to suspend. Second, since we lose connectivity during suspend, do not try joycon_init() for bluetooth controllers in the nintendo_hid_resume path. Tested via multiple suspend/resume flows when using the controller both in USB and bluetooth modes.

Esto se inform\u00f3 como un problema en dispositivos Android que usan el kernel 6.6 debido al gancho de reanudaci\u00f3n que se hab\u00eda agregado para los joycons usb. Primero, establezca un nuevo valor de estado en JOYCON_CTLR_STATE_SUSPENDED en un nintendo_hid_suspend reci\u00e9n agregado. Esto asegura que no bloquearemos el kernel esperando informes de entrada durante la suspensi\u00f3n de classdev led. Los bloqueos podr\u00edan ocurrir si la conectividad no es confiable o se pierde con el controlador antes de la suspensi\u00f3n. Segundo, dado que perdemos la conectividad durante la suspensi\u00f3n, no intentes joycon_init() para controladores bluetooth en la ruta nintendo_hid_resume. Probado a trav\u00e9s de m\u00faltiples flujos de suspensi\u00f3n/reinicio al usar el controlador en modo USB y bluetooth."
