Subject: [PATCH] iio: imu: inv_mpu6050: fix no data on MPU6050
Some chips have a fifo overflow bit issue where the bit is always
set. The result is that every data is dropped.
Change fifo overflow management by checking fifo count against
a maximum value.
Add fifo size in chip hardware set of values.

I've resolved the conflict by also queueing up 22904bdff978 ("iio: imu:
mpu6050: Add support for the ICM 20602 IMU") on 4.19.
