i3c_device_get_supported_xfer_mode() uses dev->desc to obtain the

\nbus->lock is held, and this function does not take that lock.<\/p>\n
The function only needs access to the master controller associated with

\nlifetime of the device and does not require dereferencing dev->desc.<\/p>\n","protected":false},"excerpt":{"rendered":"
