X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d86e9af6336c0ad586a5dbd70064253d40bbb5ff;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git irqchip: orion: Fix getting generic chip pointer. Enabling SPARSE_IRQ shows up a bug in the irq-orion bridge interrupt handler. The bridge interrupt is implemented using a single generic chip. Thus the parameter passed to irq_get_domain_generic_chip() should always be zero.
