Hi, I'm currently working on a spi driver for Intel platform, and when reading the various other spi drivers available in the kernel, I saw the msg->status was often updated (EINPROGRESS for example), but could not figure out who checks this status. I would have thought it would be needed to prevent concurrent access for example, but I didn't see anything in the core, nore in any driver. If it's not needed, then I would not like to carry some useless status updates in the driver I'm currently working on. Maybe I missed something... So if someone can please give some info on this, it would be great!
