2014-07-07hwmon: (adm1031) Fix writes to limit registersGuenter Roeck1-3/+5
Upper limit for write operations to temperature limit registers was clamped to a fractional value. However, limit registers do not support fractional values. As a result, upper limits of 127.5 degrees C or higher resulted in a rounded limit of 128 degrees C. Since limit registers are signed, this was stored as -128 degrees C. Clamp limits to (-55, +127) degrees C to solve the problem. Value on writes to auto_temp[12]_min and auto_temp[12]_max were not clamped at all, but masked. As a result, out-of-range writes resulted in a more or less arbitrary limit. Clamp those attributes to (0, 127) degrees C for more predictable results.

2013-01-25hwmon: Replace SENSORS_LIMIT with clamp_valGuenter Roeck1-6/+6
SENSORS_LIMIT and the generic clamp_val have the same functionality, and clamp_val is more efficient. This patch reduces text size by 9052 bytes and bss size by 11624 bytes for x86_64 builds.

2012-04-01hwmon: (adm1031) Fix compiler warningGuenter Roeck1-12/+8
Some configurations produce the following compile warning: drivers/hwmon/adm1031.c: In function 'set_fan_auto_channel': drivers/hwmon/adm1031.c:292: warning: 'reg' may be used uninitialized in this function While this is a false positive, it can easily be fixed by overloading the return value from get_fan_auto_nearest with both register value and error return code (the register value is never negative). Coincidentially, that also reduces module size by a few bytes. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Acked-by: Jean Delvare <khali@linux-fr.org>

2009-12-14i2c: Drop I2C_CLIENT_INSMOD_2 to 8Jean Delvare1-2/+1

2008-02-07hwmon: (adm1031) Fix register overwrite in set_fan_div()Jean Delvare1-2/+10
Don't rely on the register cache when setting a new fan clock divider. For one thing, the cache might not have been initialized at all if the driver has just been loaded. For another, the cached values may be old and you never know what can happen in the driver's back. Also invalidate the cache instead of trying to adjust the measured fan speed: the whole point of changing the clock divider is to get a better reading.

2006-01-05[PATCH] I2C: Remove .owner setting from i2c_driver as it's no longer neededGreg Kroah-Hartman1-1/+0
Now that i2c_add_driver() doesn't need the module owner to be set by hand, we can delete it from the drivers. This patch catches all of the drivers that I found in the current tree (if a driver sets the .owner by hand, it's not a problem, just not needed.)

2006-01-05[PATCH] i2c: Drop i2c_driver.{owner,name}, 3 of 11Laurent Riffard1-2/+4

2006-01-05[PATCH] i2c: Drop i2c_driver.flags, 2 of 3Jean Delvare1-1/+0
Just about every i2c chip driver sets the I2C_DF_NOTIFY flag, so we can simply make it the default and drop the flag. If any driver really doesn't want to be notified when i2c adapters are added, that driver can simply omit to set .attach_adapter. This approach is also more robust as it prevents accidental NULL pointer dereferences. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2005-09-05[PATCH] hwmon: hwmon vs i2c, second round (06/11)Jean Delvare1-2/+1
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.

Kill normal_isa in header files, documentation and all chip drivers, as it is no more used. normal_i2c could be renamed to normal, but I decided not to do so at the moment, so as to limit the number of changes.

The adm9240 driver, in adm9240_detect(), allocates a structure. The error path attempts to kfree() ->client field of it (second one), resulting in an oops (or slab corruption) if the hardware is not present. ->client field in adm1026, adm1031, smsc47b397 and smsc47m1 is the first in ${HWMON}_data structure, but fix them too.
