[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.
