[PATCH] iio: gyro: mpu3050: Fix error handling in mpu3050_trigger_handler

From: Dinghao Liu
Date: Mon Mar 01 2021 - 03:06:14 EST


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.
