Since 49ffcf8f99e8d33ec8afb450956804af518fd788 setting struct ctl_table.procname = NULL does no longer work as it used to the way the AX.25 code is expecting it to resulting in the AX.25 sysctl registration code to break if CONFIG_AX25_DAMA_SLAVE was not set as in some distribution kernels. Kernel releases from 2.6.24 are affected. Signed-off-by: Ralf Baechle <redacted>
