Title:
Driver build error on kernel 5.8, but works on 5.4
Status in bcmwl package in Ubuntu:
Confirmed
Bug description:
Recently kernel was updated on Focal from 5.4 to 5.8. From that moment on
WiFi doesn't work anymore. After a try rebuild (reconfigure) the result is:
---------------------------------------------------
# dpkg-reconfigure bcmwl-kernel-source
Removing all DKMS Modules
Done.
Loading new bcmwl-6.30.223.271+bdcom DKMS files...

ERROR: Cannot create report: [Errno 17] File exists:

Error! Bad return status for module build on kernel: 5.8.0-34-generic (x86_64)
Consult /var/lib/dkms/bcmwl/6.30.223.271+bdcom/build/make.log for more
information.
---------------------------------------------------
As could be seen, the build for 5.4 completes successfully (and works on same
kernel), but for 5.8 fails. Seems something is going wrong with missing
function declaration - function "ioremap_nocache", as could be seen in attached
make.log.
I'm guessing, driver code may need be updated according to the new kernel
headers.
