Hello Skari,
hello list members,
the solution is, that CONFIG_TRIM_UNUSED_KSYMS *must not* be enabled.
The error occurs if it is, and vanishes, if it is not (e.g. module
loading works).
I tried to whitelist "m88ds3103_attach", however, the build dies[1] if I
do this (many other builds to find this out suceeded).
I'm now on 6.0.2.
So either CONFIG_TRIM_UNUSED_KSYMS is broken (the help referes to
possible issues with external modules, not internal) or cx23885 needs
to depend on this option to be off (possibly as workaround).
Please tell me, what else you need to fix the kernel. Is reporting
here sufficient or should I do this elsewhere?
Thanks
Helge
