Commit Message

Arnd Bergmann Sept. 6, 2016, 2:06 p.m. UTC 
As of commit 5be9fc23cdb4 ("ARM: orion5x: fix legacy orion5x IRQ numbers"),
IRQ zero is no longer a valid interrupt on Orion5x, so we can use the
normal convention of using '0' to indicate an invalid interrupt, rather
than the deprecated NO_IRQ constant

My first approach was to pass a pointer to the resource into
orion_ge00_switch_init(), but it seemed to just add complexity
for no good.
