Merge branch irq/print_chip into irq/irqchip-next
* irq/print_chip: : . : Convert irqchip drivers that use the .name field as a topology : description to the .irq_print_chip callback, which allows the : name to be made dymanic. The irq_chip structures are then made : 'const' in order to prevent further abuse. : . irqchip/versatile-fpga: Switch to dynamic chip name output irqchip/ts4800: Switch to dynamic chip name output irqchip/mvebu-pic: Switch to dynamic chip name output irqchip/lpc32xx: Switch to dynamic chip name output irqchip/gic: Switch to dynamic chip name output genirq/debugfs: Use irq_print_chip() when provided by irqchip genirq: Allow irq_chip registration functions to take a const irq_chip irqdomain: Let irq_domain_set_{info,hwirq_and_chip} take a const irq_chip Signed-off-by: Marc Zyngier <maz@kernel.org>
