Lars-Peter Clausen 5670ed4d55 iio: inv_mpu6050: Fully validate gyro and accel scale writes 
commit e09fe9135399807b8397798a53160e055dc6c29f upstream.

When setting the gyro or accelerometer scale the inv_mpu6050 driver ignores
the integer part of the value. As a result e.g. all of 0.13309, 1.13309,
12345.13309, ... are accepted as a valid gyro scale and 0.13309 is the
scale that gets set in all those cases.

Make sure to check that the integer part of the scale value is 0 and reject
it otherwise.
