unicore32: Replace setup_irq() by request_irq() (ba947241) · Commits · 戴 / test

request_irq() is preferred over setup_irq(). Invocations of setup_irq() occur after memory allocators are ready. setup_irq() was required in older kernels as the memory allocator was not available during early boot. Hence replace setup_irq() by request_irq(). Signed-off-by:
