Fortunately there's one person that have good sources.
- Will the driver code end up in kernel one day?

As the github repository seems to belong to the person who maintains
most Realtek wi-fi drivers in mainline kernel, I guess it's him whom you
should ask about his plans about getting the driver into mainline.

The SDIO driver for the RTL8723BS is the same pile of stinking excrement as are all the Realtek drivers for USB devices, thus submission to the kernel requires many months of reworking. That applies even to staging. In addition, submission to staging also implies a commitment to eventually convert the driver for submission to the regular wireless tree. Actually, I do not expect to live long enough to be able to complete that task!

There is hope. Jes Sorensen of Red Hat is writing a new driver for Realtek USB devices called rtl8xxxu. It lacks a number of features but is very stable. At the moment, it handles RTL8723AU, RTL8188(CR)U, and RTL819(1,2)CU. Jes is working on extending it to RTL8188EU and RTL8723BU. That last device is of great interest here. Once it works, it will be quite easy to add the SDIO plumbing in place of the USB stuff to make an rtl8723bs driver. Until that happens, you will need to use the GitHub repo that is referenced above.

While awaiting the above developments, we are continuing to debug the GitHub driver to improve its stability.
