* drivers/firmware: const-ify DMI API and internalsJeff Garzik2007-10-09
| | | | | | | | | | | | | | | | | | | | | | | Three main sets of changes: 1) dmi_get_system_info() return value should have been marked const, since callers should not be changing that data. 2) const-ify DMI internals, since DMI firmware tables should, whenever possible, be marked const to ensure we never ever write to that data area. 3) const-ify DMI API, to enable marking tables const where possible in low-level drivers. And if we're really lucky, this might enable some additional optimizations on the part of the compiler. The bulk of the changes are #2 and #3, which are interrelated. #1 could have been a separate patch, but it was so small compared to the others, it was easier to roll it into this changeset.

* hwmon: (smsc47m1) restore missing name attributeJean Delvare2007-08-12
| | | | | | | | | | | | | | | The smsc47m1 driver no longer creates the name attribute used by libsensors to identify chip types. It was lost during the conversion to a platform driver. I was fooled by the fact that we do have a group with all attributes, but only to delete them all at once. The group is not used to create the attributes, so we have to explicitly create the name attribute.

* hwmon: (w83627ehf) don't assume bank 0Jean Delvare2007-08-12
| | | | | | | | | | | Don't assume that the default bank is 0. For one thing, we don't even set it to 0 when the driver is loaded, so the initial state might be different. For another, something (say, the BIOS) might access the chip and leave with the bank set to something different, so assuming that the bank value is 0 is not safe.

| | | | | | | | Commit 348753379a7704087603dad403603e825422fd9a introduced a regression that caused temp2 and temp3 sensor type settings to be written to temp1 instead. The result is that temp sensor readings could be way off. Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
* hwmon: fscher read control bugfixHans de Goede2007-07-30
| | | | | | | | | | | | Here is a small fscher bugfix for 2.6.23 merging, lifted from my other fscher work, as requested by Jean. The current driver has a control sysfs attribute, which shows the contents of the control register, but the underlying global_control value in the data structure currently never gets filled with the actual contents of this register.

* hwmon: fix lm78 detection regressionHans de Goede2007-07-30
| | | | | | | | | | | | | | | Here is a small but important bugfix to the lm78 driver. I found out about this problem because a Fedora user filed a bug that the lm78 driver no longer worked on his system: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=249428 The problem is that sometime ago the isa lm78 detection was made more stringent and this new code now checks the chip-id, but does not accept a chip-id of 20h, however a chip-id of 20h is valid, and is excepted in the main probe function of the driver, see line 551. This fixed also makes the isa detection code accept the chip-id of 0x20 fixing this issue. Signed-off-by: Hans de Goede <j.w.r.degoede@hhs.nl> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>

However some drivers omit the "input" part and create files named fan1_fault (pc87427) or temp1_fault (dme1737). And the new "generic" libsensors follows this second (non-standard) convention, so it fails to report fault conditions for drivers which follow the standard. We want a single naming scheme, and everyone seems to prefer the shorter variant, so let's go for it. Signed-off-by: Jean Delvare <khali@linux-fr.org>
