commit 82ee91d6b15f06b6094eea2c26afe0032fe8e177 upstream.
TLV493D_BX2_MAG_X_AXIS_LSB is defined as GENMASK(7, 4). FIELD_GET()
already right-shifts bits [7:4] to [3:0], so the additional >> 4
discards most of the X-axis low nibble. The Y and Z axes correctly
omit this extra shift. Remove it.

iio: magnetometer: add support for Infineon TLV493D 3D Magentic sensor2025-09-10T18:47:05ZDixit Parmardixitparmar19@gmail.com2025-09-06T08:37:57Zurn:sha1:106511d280c75908b5252e465ffb57cc66b05a2d
The Infineon TLV493D is a Low-Power 3D Magnetic Sensor. The Sensor
applications includes joysticks, control elements (white goods,
multifunction knops), or electric meters (anti tampering) and any
other application that requires accurate angular measurements at
low power consumptions.
The Sensor is configured over I2C, and as part of Sensor measurement
data it provides 3-Axis magnetic fields and temperature core measurement.
The driver supports raw value read and buffered input via external trigger
to allow streaming values with the same sensing timestamp.
While the sensor has an interrupt pin multiplexed with an I2C SCL pin.
But for bus configurations interrupt(INT) is not recommended, unless timing
constraints between I2C data transfers and interrupt pulses are monitored
and aligned.
The Sensor's I2C register map and mode information is described in product
User Manual [1].
