i was just perusing the underlying code for invoking initcalls (mostly because i forgot to return the correct value, and bricked my target board), and i see this in lib/initcall.c:
ret = (*init_fnc_ptr)(); if (ret) { printf("initcall sequence %p failed at call %p (err=%d)\n", init_sequence, (char *)*init_fnc_ptr - reloc_ofs, ret); return -1; }
so, perfectly reasonably, if an initcall returns a non-zero value, that's failure, which is why misc_init_r() should, as long as everything succeeds, return zero, correct?
but there's this in board/BuS/eb_cpu5282/eb_cpu5282.c:
int misc_init_r(void) { #ifdef CONFIG_HW_WATCHDOG hw_watchdog_init(); #endif return 1; }
i haven't dug into this any further to see if that's a special case, but isn't that going to return failure every time it's invoked?
it may be that that board doesn't define the watchdog or the use of misc_init_r(), but that just seems ... wrong? thoughts?
