Subject[PATCH AUTOSEL 4.19 36/60] genirq: Add stub for set_handle_irq() when !GENERIC_IRQ_MULTI_HANDLER
Date
From: Zhen Lei <thunder.leizhen@huawei.com>

[ Upstream commit ea0c80d1764449acf2f70fdb25aec33800cd0348 ]

In order to avoid compilation errors when a driver references set_handle_irq(),
but that the architecture doesn't select GENERIC_IRQ_MULTI_HANDLER,
add a stub function that will just WARN_ON_ONCE() if ever used.
