Sergey Shtylyov 4da83759f9 smsc911x: allow using IRQ0 ... commit 5ef9b803a4af0f5e42012176889b40bb2a978b18 upstream. The AlphaProject AP-SH4A-3A/AP-SH4AD-0A SH boards use IRQ0 for their SMSC LAN911x Ethernet chip, so the networking on them must have been broken by commit 965b2aa78f ("net/smsc911x: fix irq resource allocation failure") which filtered out 0 as well as the negative error codes -- it was kinda correct at the time, as platform_get_irq() could return 0 on of_irq_get() failure and on the actual 0 in an IRQ resource. This issue was fixed by me (back in 2016!), so we should be able to fix this driver to allow IRQ0 usage again... When merging this to the stable kernels, make sure you also merge commit e330b9a6bb ("platform: don't return 0 from platform_get_irq[_byname]() on error") -- that's my fix to platform_get_irq() for the DT platforms...
