Hi Krzysztof,
[...]
+static void __iomem *fimc_is_get_pmu_regs(struct device *dev)
+{
+ struct device_node *node;
+ void __iomem *regs;
+
+ node = of_parse_phandle(dev->of_node, "samsung,pmu-syscon", 0);
+ if (!node) {
+ dev_warn(dev, "Finding PMU node via deprecated method, update your DTB\n");
+ node = of_get_child_by_name(dev->of_node, "pmu");
+ if (!node)
+ return IOMEM_ERR_PTR(-ENODEV);
in my opinion this should be:
...
if (!node)
return IOMEM_ERR_PTR(-ENODEV);
dev_warn(dev, "Finding PMU node via deprecated method, update your DTB\n");
Because if you don't have both "samsung,pmu-syscon and "pmu" then
the warning should not be printed and you need to return -ENODEV.
... and... "*please* update your DTB", the user might get upset
and out of sheer spite, decides not to do it – just because! :)
