From: Grant Likely Date: Thu, 4 Oct 2007 06:52:40 +0000 (+0200) Subject: Sysace: Don't enable IRQ until after interrupt handler is registered X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d2bbf3da3759d04cd5836955cc59c8ae96092831;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git Sysace: Don't enable IRQ until after interrupt handler is registered The previous patch to move the interrupt handler registration moved it below enabling interrupts which could be a problem if the device is on a shared interrupt line. This patch fixes the order.
