Refer to Intel SDM for details on the MSR: MSR_TEMPERATURE_TARGET.

because the thermal framework are required to be ready as early as

This simplifies getting the 'driver_data' from 'struct device' directly.
Going through platform_device or pci_dev is not required. Also removes
condition check as the private data stored with dev pointer, means
irrespective of enumeration mode, we can use dev_get_drvdata().
This removes the unnecessary step back and forth.

Pull thermal management fixes from Zhang Rui:
- Fix a race condition that sysfs could be accessed before necessary
initialization in int340x thermal driver. (Aaron Hill)
- Fix a NULL vs IS_ERR() check in int340x thermal driver. (Dan
Carpenter)
* 'for-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux:
drivers: thermal: int340x_thermal: Fix sysfs race condition
thermal: int340x_thermal: Fix a NULL vs IS_ERR() check
Changes since V1:
* Use dev_info instead of printk
* Use dev_warn instead of BUG_ON
Previously, sysfs_create_group was called before all initialization had
fully run - specifically, before pci_set_drvdata was called. Since the
sysctl group is visible to userspace as soon as sysfs_create_group
returns, a small window of time existed during which a process could read
from an uninitialized/partially-initialized device.
This commit moves the creation of the sysctl group to after all
initialized is completed. This ensures that it's impossible for
userspace to read from a sysctl file before initialization has fully
completed.
To catch any future regressions, I've added a check to ensure
that proc_thermal_emum_mode is never PROC_THERMAL_NONE when a process
tries to read from a sysctl file. Previously, the aforementioned race
condition could result in the 'else' branch
running while PROC_THERMAL_NONE was set,
leading to a null pointer deference.

satisfied implicitly through dependencies on CONFIG_ACPI have to be
specified directly.
IOSF_CORE depends on PCI. For this reason, add a direct dependency on
CONFIG_PCI.
