Is this related to an Issue or why do You show that? If You have a specific Issue, it would be good to describe it.
when I give the command journalctl -p err, it gives me these messages, I don't know what it is related to.

When You don't have an Issue with the System of some kind, I would it see as a minor Thing what You can ignore. But You can wait for other Users here and what they think about that.
So, you don't know why these warnings are in the system? I thought it might help with these little problems. Can you tell me if the PRO version has any tool I can fix?
That what You show are Logs. System Logs. There can be Stuff like that but that doesn't mean that there is automatically a Problem.
A Macbook Air would not have any SPI attachments on PCI slots. So this would not apply to you.
If checking error logs, you will always see errors because the kernel of any O.S., Mac, Linux or Windows, runs by checking if present, using fallback if not, and logging the failure to find the non-present node, module, hardware, etc.
If you are not having issues, good.
But this is the only error I see that would cause concern.
The proprietary driver is giving a memory safety error.
If you experience problems with wifi, you might try
sudo apt remove bcmwl-kernel-source
sudo apt install firmware-b43-installer
Or using the open source driver.
