== Impact ==
0cf3:535b is not full functioning with the current in-kernel driver. For example, it doesn't work with a BLE keyboard.

== Fix ==
It is a QCA_ROME device. Should mark it so in the device ID table to make it work properly.

== Test Case ==
Try to use this module with a BLE keyboard. It is expected to work without problem, but instead it can't even find the keyboard.

== Risk of Regression ==
Very low. This is already in upstream, and proved working in QA lab.
