Commit Message

Zhang Lixu March 17, 2025, 1:36 a.m. UTC 
On Intel platforms, the HID_USAGE_SENSOR_HUMAN_PROXIMITY report size is 16
bits. This patch adds support for handling 16-bit report sizes for the
HID_USAGE_SENSOR_HUMAN_PROXIMITY usage in the HID sensor proximity driver.

Previously, the driver only supported 8-bit and 32-bit report sizes. With
this change, the driver can now correctly process 16-bit proximity data,
ensuring accurate human presence detection on platforms where this report
size is used.
