2019-04-15hwmon: (adm9240) Use permission specific SENSOR[_DEVICE]_ATTR variantsGuenter Roeck
Use SENSOR[_DEVICE]_ATTR[_2]_{RO,RW,WO} to simplify the source code, to improve readbility, and to reduce the chance of inconsistencies. Also replace any remaining S_<PERMS> in the driver with octal values. The conversion was done automatically with coccinelle. The semantic patches and the scripts used to generate this commit log are available at https://github.com/groeck/coccinelle-patches/. This patch does not introduce functional changes. It was verified by compiling the old and new files and comparing text and data sizes. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2017-01-02hwmon: (adm9240) use permission-specific DEVICE_ATTR variantsJulia Lawall
Use DEVICE_ATTR_RO for read only attributes and DEVICE_ATTR_RW for read/write attributes. This simplifies the source code, improves readbility, and reduces the chance of inconsistencies. The conversion was done automatically using coccinelle. It was validated by compiling both the old and the new source code and comparing its text, data, and bss size.

2016-12-09hwmon: (adm9240) Fix overflows seen when writing into limit attributesGuenter Roeck
Module test reports: in0_min: Suspected overflow: [3320 vs. 0] in0_max: Suspected overflow: [3320 vs. 0] in4_min: Suspected overflow: [15938 vs. 0] in4_max: Suspected overflow: [15938 vs. 0] temp1_max: Suspected overflow: [127000 vs. 0] temp1_max_hyst: Suspected overflow: [127000 vs. 0] aout_output: Suspected overflow: [1250 vs. 0] Code analysis reveals that the overflows are caused by conversions from unsigned long to long to int, combined with multiplications on passed values.

2016-10-17hwmon: (adm9240) handle temperature readings below 0Chris Packham
Unlike the temperature thresholds the temperature data is a 9-bit signed value. This allows and additional 0.5 degrees of precision on the reading but makes handling negative values slightly harder. In order to have sign-extension applied correctly the 9-bit value is stored in the upper bits of a signed 16-bit value. When presenting this in sysfs the value is shifted and scaled appropriately.

2006-01-05[PATCH] I2C: Remove .owner setting from i2c_driver as it's no longer neededGreg Kroah-Hartman
Now that i2c_add_driver() doesn't need the module owner to be set by hand, we can delete it from the drivers.

2006-01-05[PATCH] i2c: Drop i2c_driver.flags, 2 of 3Jean Delvare
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 (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.
