| Subject: ARM: mach-shmobile: sh73a0 IRQ sparse alloc fix |
| |
| Fix the sh73a0 external IRQ pin code to properly support |
| CONFIG_SPARSE_IRQ=y by allocating IRQ descriptors for the |
| cascaded IRQs associated with external IRQ pins. |
| |
| Without this fix it is impossible to request IRQ0->IRQ31 |
| on the Kota2 board when sparse IRQs are enabled. |
