If the 'queue_priority_mapping' is not provided, we need to allocate the correct amount of memory. Each entry takes 2 s8, so actually less memory than needed is allocated. Update the size of each entry when the memory is devm_kcalloc'ed. Fixes: 6d10c3950bf4 ("ARM: edma: Get IP configuration from HW (number of channels, tc, etc)") Signed-off-by: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx> --- Note that the devm_kcalloc() in edma_xbar_event_map() looks also spurious. However, this looks fine to me because of the 'nelm >>= 1;' before the 'for' loop. --- drivers/dma/ti/edma.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/dma/ti/edma.c b/drivers/dma/ti/edma.c index 3ea8ef7f57df..f313e2cf542c 100644 --- a/drivers/dma/ti/edma.c +++ b/drivers/dma/ti/edma.c @@ -2121,7 +2121,7 @@ static int edma_setup_from_hw(struct device *dev, struct edma_soc_info *pdata, * priority.
