iio: accel: mma8452: handle I2C read error(s) in mma8452_read()
Overview
Description
In the Linux kernel, the following vulnerability has been resolved: iio: accel: mma8452: handle I2C read error(s) in mma8452_read() Currently, If i2c_smbus_read_i2c_block_data() fails but mma8452_set_runtime_pm_state() succeeds, mma8452_read() returns 0. As a result, the caller mma8452_read_raw() assumes the read was successful and proceeds to use a buffer containing uninitialized stack memory. Add proper checking of the I2C read return value and propagate errors to the caller.

Solution
Fix uninitialized memory usage by checking I2C read return values.
- Check I2C read return value.
- Propagate I2C read errors to the caller.
- Ensure buffer contains initialized data.
