[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. File: linux/arch/arm/mach-s3c2410/dma.c Fix: trivial, below Signed-off-by: Albrecht Dreß Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
