It is possible that platform_get_resource() might return NULL and therefore code needs to check for this condition before de-referencing the pointer. Therefore move the de-referencing of 'res' pointer after devm_ioremap_resource() which would have checked the validity of the pointer Reported-by: Dan Murphy <dmurphy@ti.com> Signed-off-by: Vignesh Raghavendra <vigneshr@ti.com> --- drivers/mfd/ti_am335x_tscadc.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
