2017-10-29hwmon: (stts751) Fix buffer size passed to snprintfJean Delvare1-9/+9
Function snprintf already cares for the terminating NUL at the end of the string, the caller doesn't need to do it. Signed-off-by: Jean Delvare <jdelvare@suse.de> Cc: Andrea Merello <andrea.merello@gmail.com> Cc: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2017-08-13hwmon: (stts751) buffer overrun on wrong chip configurationAnton Vasilyev1-0/+4
If stts751 hw by some reason reports conversion rate bigger then 9: ret = i2c_smbus_read_byte_data(priv->client, STTS751_REG_RATE); then dereferencing stts751_intervals[priv->interval] leads to buffer overrun. The patch adds sanity check for value stored on chip. Found by Linux Driver Verification project (linuxtesting.org).

2017-04-02hwmon: (stts751) Add OF device ID tableJavier Martinez Canillas1-0/+7
The driver doesn't have a struct of_device_id table but supported devices are registered via Device Trees. This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:<device>. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF.
