** Description changed: - This bug is for tracking purpose + This SRU template is for linux-firmware: + + BugLink: https://bugs.launchpad.net/bugs/2060904 + + [Impact] + + On a Dell laptop, let it connect to a WiFi router, connect a BT + device, then disconnect it, connect the bt device again, we expect + the device could be connected successfully, but it couldn't and + the BT firmeware crashed. + + [Fix] + + Need to upgrade the firmware for RTL8852CE and cherry-pick 2 kernel + patches, here we send the MR for firmware first. And it is backward + compatible, the upgraded firmware could work with kernel without + those 2 patches as well as before. + + [Test Case] + + With the upgraded firmware + kernel without the 2 kernel patches, + the wifi and bt could work as well / bad as before. + + With the upgraded firmware + kernel with the 2 kernel patches, bt + firmware will not crash anymore and bt could connect / disconnect + many many bt devices. + + [Where problems could occur] + + This MR comes from upstream commit, it has low possibility to + introduce regression. If the bt or wifi on this laptop couldn't + work as well as before, it is possible that this MR introduces + regression. According to our test, the wifi and bt could work well + with upgraded firmware.
