Subject: [PATCH 0/2] media: dvb-usb-v2: add init_ready flag to prevent  race during device initialization

This patch series introduces an atomic init_ready flag in 
struct dvb_usb_device and adds checks in relevant code paths. 
Drivers now verify that device initialization has completed before 
performing operations that rely on initialized device state. 
If the device is not yet ready, the operation is deferred until 
initialization finishes, preventing race conditions and improving 
driver robustness.
