irqchip/tb10x: Consolidate chained IRQ handler install/remove
Chained irq handlers usually set up handler data as well. We now have a function to set both under irq_desc->lock. Replace the two calls with one. Search and conversion was done with coccinelle: @@ expression E1, E2, E3; @@ ( -if (irq_set_handler_data(E1, E2) != 0) - BUG(); | -irq_set_handler_data(E1, E2); ) -irq_set_chained_handler(E1, E3); +irq_set_chained_handler_and_data(E1, E3, E2); @@ expression E1, E2, E3; @@ ( -if (irq_set_handler_data(E1, E2) != 0) - BUG(); ... | -irq_set_handler_data(E1, E2); ... ) -irq_set_chained_handler(E1, E3); +irq_set_chained_handler_and_data(E1, E3, E2); Reported-by: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: Julia Lawall <Julia.Lawall@lip6.fr> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Jason Cooper <jason@lakedaemon.net>
