I have to admit that I can't really see myself carding deeply about
SH, but somebody else may. I don't think I've gotten an arch/sh pull
in a couple of years.
That said, I also don't see anything wrong with the arch/sh version of
BUG() and friends, so I don't see why this would hit arch/sh and not
somebody else.
I _assume_ it is the BUG_ON() in hwrng_modexit() that triggers this:
static void __exit hwrng_modexit(void)
{
mutex_lock(&rng_mutex);
BUG_ON(current_rng);
kfree(rng_buffer);
...
but again, I don't see what's special about sh here apart from maybe
"not well maintained binutils support".
Does removing the BUG_ON() fix the build?
None of this is at all new, though. Funky.
