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. Signed-off-by: Alexander Shishkin Reviewed-by: Laurent Fert

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. Signed-off-by: Dan Carpenter Signed-off-by: Alexander Shishkin Signed-off-by: Greg Kroah-Hartman
