To be honest I prefer the ifdef approach as it is more explicit and does not feel like a cheat. Hi, You are welcome to merge (or ack or have someone else merge) either of them. I'm not counting patches, just trying to help out (in this case by reducing noise). > Actually some of the functions are between a flag already PRISM2_NO_PROCFS_DEBUG which is in a private header file hostap_config.h. Seems like this would be better placed in Kconfig and depend on CONFIG_PROCFS. Anyway, this driver is old cruft. Maybe some people are still running it, but it is probably not worth the effort so fine with either fix. > > Regards, > Arend -- ~Randy
