ERROR: "__bad_ndelay" [drivers/media/platform/s5p-jpeg/s5p-jpeg.ko] undefined! That happens because asm-generic doesn't like any ndelay time bigger than 20us. Currently, usleep_range() couldn't simply be used, since exynos4_jpeg_sw_reset() is called with a spinlock held. So, let's use udelay() instead.
