    Note that it had been allowed until my (erroneous?) commit 
33c133cc7598e60976a069344910d63e56cc4401 ("phy: IRQ cannot be shared"), so I'd 
like this commit just reverted instead...
    I'm not sure now what was the reason I concluded that the IRQ sharing was 
impossible... most probably I thought that the kernel IRQ handling code exited 
the loop over the IRQ actions once IRQ_HANDLED was returned -- which is 
obviously not so in reality...
