Subject: [PATCH] genirq/generic-chip: Fix the irq_chip name for
/proc/interrupts
irq_init_generic_chip() only sets the name for the first chip type, which
leads to empty names for other chip types. Eventually, these names will be
shown as "-" /proc/interrupts.
Set the name for all chip types by default.
