This seems like a bug in the USB bits in stand instead. In the kernel
SYSINIT and SYSUNINIT use separate namespace by appending different suffixes
to the first parameter:
DATA_SET(sysinit_set,uniquifier ## _sys_init)
vs.
DATA_SET(sysuninit_set,uniquifier ## _sys_uninit)
The bug is in stand/kshim/bsd_kernel.h:
#define SYSINIT(uniq, subs, order, _func, _data) \
const struct sysinit UNIQ_NAME(sysinit_##uniq) = { \
.func = (_func), \
.data = __DECONST(void *, _data) \
}; \
SYSINIT_ENTRY(uniq##_entry, "sysinit", (subs), \
(order), "const struct sysinit", \
UNIQ_NAME_STR(sysinit_##uniq), "SYSINIT")
#define SYSUNINIT(uniq, subs, order, _func, _data) \
const struct sysinit UNIQ_NAME(sysuninit_##uniq) = { \
.func = (_func), \
.data = __DECONST(void *, _data) \
}; \
SYSINIT_ENTRY(uniq##_entry, "sysuninit", (subs), \
(order), "const struct sysuninit", \
UNIQ_NAME_STR(sysuninit_##uniq), "SYSUNINIT")
This should be using uniq##_uninit_entry or some such for the first argument
to SYSINIT_ENTRY().
