Subject: genirq: fix name space collision of nr_irqs in autoprobe.c
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=63d659d556f145d33798b8ad19ced10c254fe445;p=linux-beck.git

genirq: fix name space collision of nr_irqs in autoprobe.c

probe_irq_off() is disfunctional as the local nr_irqs is referenced
instead of the global one for the for_each_irq_desc() iterator.
