The patch d85a2d61432a: "ARM: OMAP2+: Populate legacy resources for
dma and smartreflex" from Oct 10, 2017, leads to the following Smatch
complaint:
arch/arm/mach-omap2/omap_device.c:453 omap_device_copy_resources()
error: we previously assumed 'oh' could be null (see line 394)
arch/arm/mach-omap2/omap_device.c
393
394 if (!oh || !oh->od || !oh->od->pdev) {
^^^
Patch adds check for NULL.
395 error = -EINVAL;
396 goto error;
397 }

452 error:
453 WARN(error, "%s: %s device %s failed: %i\n",

and the patch adds a dereference.
