Guenter Roeck 648cd48c9e hwmon: Do not accept invalid name attributes
hwmon name attributes must not include '-', as specified in
Documentation/hwmon/sysfs-interface. Also filter out spaces,
tabs, wildcards, and newline characters.

Guenter Roeck 74188cba08 hwmon: Provide managed hwmon registration
Drivers using the new hwmon_device_register_with_groups API often have a
remove function which consists solely of a call hwmon_device_unregister().

Provide support for devm_hwmon_device_register_with_groups and
devm_hwmon_device_unregister to allow this repeated code to be removed
and help eliminate error handling code.

Guenter Roeck bab2243ce1 hwmon: Introduce hwmon_device_register_with_groups
hwmon_device_register_with_groups() lets callers register a hwmon device
together with all sysfs attributes in a single call.

When using hwmon_device_register_with_groups(), hwmon attributes are attached
to the hwmon device directly and no longer with its parent device.

Jean Delvare d6dab7dd12 hwmon: Fix PCI device reference leak in quirk
Thankfully this only affects systems with one specific south bridge
and is most probably harmless unless the hwmon module is heavily
cycled.

Jonathan Cameron 4ca5f468cc hwmon: convert idr to ida and use ida_simple interface
hwmon was using an idr with a NULL pointer, so convert to an
ida which then allows use of Rusty's ida_simple_get.

Jean Delvare 2958b1ec6b hwmon: PCI quirk for hwmon access on MSI MS-7031 board
The MSI MS-7031 is based on an ATI IXP300 south bridge. On this south
bridge, accessible I/O ports must be enabled explicitly. Unfortunately
the BIOS forgets to enable access to the hardware monitoring chip I/O
ports, so hardware monitoring fails.

Add a quirk enabling access to the required ports (0x295-0x296). This
is exactly what MSI's own hardware monitoring application is doing, so
it has to be the right way.

David Brownell 37f54ee546 hwmon: Use subsys_initcall
Subsystem infrastructure should normally register with "subsys_initcall",
so that it's available to drivers that may need to initialize early.

This patch updates "hwmon" to do so.  It's common for embedded systems to
have multifunction chips with hardware monitoring interfaces, and to have
those chips be used during system bringup ... before a normal "module_init"
would kick, or maybe just linked so they'd init before hwmon.

Mark M. Hoffman ded2b66615 [PATCH] hwmon: add required idr locking
Add required locking around idr_ routines, retry the idr_pre_get/idr_get_new
pair properly, and sprinkle in some likely/unlikely for good measure.

(Lack of idr locking didn't hurt when all callers were I2C clients, as the
i2c-core serialized for us anyway.  Now that we have non I2C hwmon drivers,
this is truly necessary.)
