From: Dinghao Liu <dinghao....@zju.edu.cn> commit 6dbbbe4cfd398704b72b21c1d4a5d3807e909d60 upstream.
There is one regmap_bulk_read() call in mpu3050_trigger_handler that we have caught its return value bug lack further handling. Check and terminate the execution flow just like the other three regmap_bulk_read() calls in this function.
