From: Russell King Date: Sun, 4 Sep 2005 18:45:00 +0000 (+0100) Subject: [ARM] Wrap calls to descriptor handlers X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=664399e1fbdceb18da9c9c5534dedd62327c63e8;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git [ARM] Wrap calls to descriptor handlers This is part of Thomas Gleixner's generic IRQ patch, which converts ARM to use the generic IRQ subsystem. Here, we wrap calls to desc->handler() in an inline function, desc_handle_irq(). This reduces the size of Thomas' patch since the changes become more localised.
