2005-11-23[PATCH] hwmon: Fix missing boundary check when setting W83627THF in0 limitsYuan Mu
Add SENSORS_LIMIT in store VCore limit functions. This fixes a potential u8 overflow on out-of-range user input. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-10-28[PATCH] hwmon: Drop useless w83627hf initialization stepJean Delvare
Drop a useless initialization step in the w83627hf driver. The comment says that the W83627HF PWM2 can be disabled, but it can't. I suppose this is a leftover from the w83781d driver (from which the w83627hf driver is derived), as for example the W83782D had the ability to disable PWM2.

2005-10-28[PATCH] hwmon: Fix w83627ehf/hf vs PNPACPI conflict (bug #4014)Petr Vandrovec
This patch changes w83627hf and w83627ehf drivers to reserve only ports 0x295-0x296, instead of full 0x290-0x297 range. While some other sensors chips respond to all addresses in 0x290-0x297 range, Winbond chips respond to 0x295-0x296 only (this behavior is implied by documentation, and matches behavior observed on real systems). This is not problem alone, as no BIOS was found to put something at these unused addresses, and sensors chip itself provides nothing there as well. But in addition to only respond to these two addresses, also BIOS vendors report in their ACPI-PnP structures that there is some resource at I/O address 0x295 of length 2. And when later this hwmon driver attempts to request region with base 0x290/length 8, it fails as one request_region cannot span more than one device. Due to this we have to ask only for region this hardware really occupies, otherwise driver cannot be loaded on systems with ACPI-PnP enabled.

2005-10-28[PATCH] hwmon: Discard bogus comment about init setting limitsJean Delvare
Discard a common out-of-date comment in 5 hardware monitoring drivers. The hardware monitoring chip drivers are no more setting sensor limits at initialization time, for quite some time already.

2005-09-09[PATCH] hwmon: w83627hf: no reset by defaultJean Delvare
Make the reset of the chips in w83627hf optional rather than the default. This reset has been causing trouble several times already. It may even go completely away unless it proves to be useful to at least one user.

2005-09-05[PATCH] hwmon: hwmon vs i2c, second round (07/11)Jean Delvare
The only part left in i2c-sensor is the VRM/VRD/VID handling code. This is in no way related to i2c, so it doesn't belong there. Move the code to hwmon, where it belongs. Note that not all hardware monitoring drivers do VRM/VRD/VID operations, so less drivers depend on hwmon-vid than there were depending on i2c-sensor.

2005-09-05[PATCH] hwmon: hwmon vs i2c, second round (06/11)Jean Delvare
The only thing left in i2c-sensor.h are module parameter definition macros. It's only an extension of what i2c.h offers, and this extension is not sensors-specific. As a matter of fact, a few non-sensors drivers use them. So we better merge them in i2c.h, and get rid of i2c-sensor.h altogether.

2005-09-05[PATCH] hwmon: tag super-i/o find functions __initJean Delvare
Super-I/O find functions in hardware monitoring drivers can be tagged __init as they are only called from functions themselves tagged __init. Two of them (smsc47b397 and w83627ehf) already do, but the other four of them (it87, pc87360, smsc47m1 and w83627hf) did not. This saves a few bytes of memory after the drivers are loaded, 192 in the case of the it87 driver. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2005-09-05[PATCH] I2C: refactor message in i2c_detach_clientJean Delvare
We could refactor the error message 34 different i2c drivers print if i2c_detach_client() fails in this function itself. Saves quite a few lines of code. Documentation is updated to reflect that change. Note that this patch should be applied after Rudolf Marek's w83792d patches.

2005-09-05[PATCH] I2C: Separate non-i2c hwmon drivers from i2c-core (5/9)Jean Delvare
Call the ISA chip drivers detection function directly instead of relying on i2c_detect. The net effect is that address lists won't be handled anymore, but they were mostly useless in the ISA case anyway (pc87360, smsc47m1, smsc47b397 had already dropped them). We don't need to handle multiple devices, all we may need is a way to force a given address instead of the original one (some drivers already do: sis5595, via686a, w83627hf), and, for drivers supporting multiple chips, a way to force one given kind. All this may be added later on demand, but I actually don't think there will be much demand. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2005-09-05[PATCH] I2C: Separate non-i2c hwmon drivers from i2c-core (3/9)Jean Delvare
Convert the 10 ISA hardware monitoring drivers (it87, lm78, pc87360, sis5595, smsc47b397, smsc47m1, via686a, w83627hf, w83627ehf, w83781d) to explicitely register with i2c-isa. For hybrid drivers (it87, lm78, w83781d), we now have two separate instances of i2c_driver, one for the I2C interface of the chip, and one for ISA interface. In the long run, the one for ISA will be replaced with a different driver type. At this point, all drivers are working again, except for missing dependencies in Kconfig.

2005-07-11[PATCH] I2C: Move hwmon drivers (2/3)Jean Delvare
