Subject[PATCH 1/3] irqchip: xilinx: Avoid __init macro usage for xilinx_intc_of_init
Date
This patch ensures that xilinx_intc_of_init API is not allocated into
the .init.text section. Since this API calls the API set_handle_irq
which uses __init macro to be put into .init.text section, this patch
makes changes to ensure that set_handle_irq also does not stay in
.init.text section.
This patch is in preparation for the patch through which the xilinx
intc driver will be loaded and unloaded as a module.
