hwmon: (iio_hwmon) fix memory leak in name attribute
The "name" variable's memory is now freed when the device is destructed thanks to devm function. Signed-off-by: Quentin Schulz <quentin.schulz@free-electrons.com> Reported-by: Guenter Roeck <linux@roeck-us.net> Fixes: e0f8a24e0edfd ("staging:iio::hwmon interface client driver.") Fixes: 61bb53bcbdd86 ("hwmon: (iio_hwmon) Add support for humidity sensors") Signed-off-by: Guenter Roeck <linux@roeck-us.net>
