Hi Thomas,

First bad commit (maybe != root cause):

commit: 6ef92063bf94cd8a6fa9fea3a82596955eb25424 net: korina: Make driver COMPILE_TESTable
date: 2 years, 8 months ago
config: sh-randconfig-r133-20231118 (https://download.01.org/0day-ci/archive/20231205/202312050130.ryR55KTq-lkp@xxxxxxxxx/config)
compiler: sh4-linux-gcc (GCC) 13.2.0
