This was non-trivial to get right because commits c23bc382ef0e ("coresight: etm4x: Refactor probing routine") and 5214b563588e ("coresight: etm4x: Add support for sysreg only devices") changed the code flow considerably. With this change the driver can be built again.

Sure, here it comes. As I'm unsure if you want to squash it into the merge or want to keep it separate I crafted a commit message. If you prefer squashing feel free to do so. This change corresponds to the merge resolution I suggested before. Best regards Uwe drivers/hwtracing/coresight/coresight-etm4x-core.c | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-)
