Title
media: pvrusb2: fix memory leak in pvr_probe
Summary
In the Linux kernel, the following vulnerability has been resolved: media: pvrusb2: fix memory leak in pvr_probe The error handling code in pvr2_hdw_create forgets to unregister the v4l2 device. When pvr2_hdw_create returns back to pvr2_context_create, it calls pvr2_context_destroy to destroy context, but mp->hdw is NULL, which leads to that pvr2_hdw_destroy directly returns. Fix this by adding v4l2_device_unregister to decrease the refcount of usb interface.

Cuando pvr2_hdw_create regresa a pvr2_context_create, llama a pvr2_context_destroy para destruir el contexto, pero mp-\u0026gt;hdw es NULL, lo que provoca que pvr2_hdw_destroy regrese directamente. Para solucionar esto, agregue v4l2_device_unregister para reducir el recuento de referencias de la interfaz
