On my tests:

Prior to this patch: with the internal ROM SDMA firmware I got UART
issues when communicating through a Bluetooth module. With external
SDMA firmware (version 3.1) it worked fine.

With your patch applied: Bluetooth worked fine even with no external
SDMA firmware, which does not match the comments you added.

Can't you just remove these comments?

Thanks
