Re: [PATCH v9 05/11] serial: 8250: expose RX trigger controls for custom callbacks

[sashiko-bot@kernel.org]

> The rx_trig_bytes attribute dispatches to a port's get_rxtrig and
> set_rxtrig callbacks when present, but the attribute group is registered
> only when the port type has a static receive-trigger table.
> 
> Allow a port that supplies both callbacks to expose the attribute without
> a static table. This lets integrations such as Octeon provide their
> FIFO-relative thresholds through callbacks while retaining their existing
> port type. Require both callbacks because the attribute is read/write;
> ports with a static table continue to use the existing fallback handlers.
