[PATCH] powerpc/fsl: Use irq_data_get_irq_handler_data() in chain handler
From: Geert Uytterhoeven <geert@linux-m68k.org>

If you already have a pointer to a struct irq_data , it's more efficient to use irq_data_get_irq_handler_data(). irq_get_handler_data() has to look up the struct irq_desc pointer again, which was already passed to the chain handler. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> --- Completely untested, not even compile-tested. If this is correct, there are probably more of these? arch/powerpc/sysdev/fsl_msi.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-)

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
