m68k/psc: Fix race in installing chained IRQ handler
Fix a race where a pending interrupt could be received and the handler called before the handler's data has been setup, by converting to irq_set_chained_handler_and_data(). Search and conversion was done with coccinelle: @@ expression E1, E2, E3; @@ ( -if (irq_set_chained_handler(E1, E3) != 0) - BUG(); | -irq_set_chained_handler(E1, E3); ) -irq_set_handler_data(E1, E2); +irq_set_chained_handler_and_data(E1, E3, E2); @@ expression E1, E2, E3; @@ ( -if (irq_set_chained_handler(E1, E3) != 0) - BUG(); ... | -irq_set_chained_handler(E1, E3); ... ) -irq_set_handler_data(E1, E2); +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: Joshua Thompson <funaho@jurai.org> Cc: Geert Uytterhoeven <geert@linux-m68k.org> Cc: linux-m68k@lists.linux-m68k.org
