Bug Description
[SRU Justification]
[Impact]
rtl8821ce-dkms fails to build against v5.10 kernels. While oem-5.10 kernel is being backported to Focal, some models of rtl8821ce would fail with built-in rtw88 driver and yet this rtl8821ce-dkms fails to build from source.
[Test Case]
Install linux-headers-
[Where problems could occur]
While this is still not the in-tree official kernel driver, the fix is not verified by the kernel community and may cause unknown behavior and/or security weakness with new kernel versions. Always use with cautions.
========== original bug report ==========
upgrade to 5.10 kernel headers causes rebuild of rtl8821ce-dkms to fail due to missing symbols as per make.log
