Subject: xtensa: define NO_IRQ appropriately for the architecture
X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b44b10c61a8fd49836071fad278bab53d0f8e510;p=pandora-kernel.git

xtensa: define NO_IRQ appropriately for the architecture

Interrupt number zero (0) is valid for the Xtensa port,
so define NO_IRQ as (-1).  And use it to override the 8250 driver
hack that compares interrupt numbers with 0 instead of NO_IRQ.
