commit 33c133cc75
("phy: IRQ cannot be shared")
On hardware with multiple PHY devices hooked up to the same IRQ line, allow
them to share it.
Sergei Shtylyov says:
"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..."
