Alexander Shishkin	e8644e4c2a	intel_th: pti: Create sysfs attributes using core driver's facility ... The core intel_th driver allows subdevices to bring in their sysfs attributes. Use this instead of taking care of them in probe and remove.

Dan Carpenter	73061da07d	intel_th: Check for NULL instead of ERR_PTR ... devm_ioremap() returns NULL on error, it doesn't return an ERR_PTR, which is what the current code does. This patch corrects these checks.
