Albrecht Dreß 105bb2698b [PATCH] ARM: 2694/1: [s3c2410/dma] release irq properly to fix kernel oops
Patch from Albrecht Dreß

Problem:
When a module requests a DMA channel via the function s3c2410_dma_request(), this function requests the appropriate irq under the name of the client module. When the client module is unloaded, it calls s3c2410_dma_free() which does not free the irq. Consequently, when e.g. running "cat /proc/interrupts", the irq owner points to freed memory, leading to a kernel oops.
