dynamic stack allocation in kernel is considered bad as kernel stack is low and we get warns on few archs as reported by kbuild test robot >> drivers/dma/sh/shdma-base.c:671:32: sparse: Variable length array is used. >> drivers/dma/sh/shdma-base.c:701:1: warning: 'shdma_prep_dma_cyclic' uses >> dynamic stack allocation [enabled by default] Fix this by making a static array of 32 which should be sufficient for shdma_prep_dma_cyclic which only user in kernel is audio and 32 periods for audio seems quite sufficient atm Reported-by:
