Subject: Added empty IRQ backend.
X-Git-Tag: V2.16~245
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=673b27cc1b8fa0d7a7004ab715f03c229826cbd9;p=cc65

Added empty IRQ backend.

The driver kernels all require IRQ handling even if the actual drivers don't make use of it. So in order to successfully link a NES program using the joystick and/or TGI driver there has to be at least a "dummy" IRQ backend.
