Hi,

Thanks for review.

You do not free rd anywhere in your code.

OK, I missed that, corrected in v4.

+static int exynos_srom_probe(struct platform_device *pdev)
+{
+       struct device_node *np;
+       struct device *dev = &pdev->dev;
+
+       np = dev->of_node;

Are you sure that dev->of_node will be always set ?
I see lots of driver who if (dev->of_node) {}

Taken care in v4.

+       exynos_srom_base = of_iomap(np, 0);
+
+       if (!exynos_srom_base) {
+               pr_err("iomap of exynos srom controller failed\n");
+               return -ENOMEM;
+       }

You can use dev_err(dev, "") insted of pr_err

Taken care in v4.

+
+       exynos_srom_regs = exynos_srom_alloc_reg_dump(exynos_srom_offsets,
+                       sizeof(exynos_srom_offsets));
+
+       if (!exynos_srom_regs) {
+               iounmap(exynos_srom_regs);
+               return -ENOMEM;
+       }
+
+       return 0;
+}

Instead of using a global static exynos_srom_base/exynos_srom_regs, why you do not use platform_set_drvdata() ?

OK. Taken care in v4.

Posted v4 here
