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... > Signed-off-by: Nathan Sullivan > Signed-off-by: Xander Huff > Acked-by: Ben Shelton > Acked-by: Jaeden Amero [...] MBR, Sergei
