Hi,

This series contains a set of small fixes and improvements for the hx9023s
proximity sensor driver.

The changes include:

- Fixing a potential out-of-bounds access when copying firmware data.
- Avoiding a division-by-zero case when the sampling frequency is unspecified.
- Allowing the firmware file name to be specified via firmware-name property,
  along with the corresponding DT binding update.

All changes are independent but related to robustness and platform support,
and are grouped together for easier review.

Tested on a DT-based platform with firmware loading enabled.

Thanks for your time and review.

Best regards,
Yasin Lee

- Patch 4 (driver): 
    - Fixed variable declaration order (reverse xmas tree)
    - Split declaration and assignment for fw_name
    - Removed unnecessary error checking for device_property_read_string()
    - Simplified to: fw_name = "hx9023s.bin"; device_property_read_string(...);
- Patch 5: Temporarily dropped (ACPI support)
    - Will resubmit separately once TYHX vendor ID is officially registered with UEFI Forum
    - Need to provide verified DSDT evidence
- Link to v1: https://lore.kernel.org/r/20260209-upstream-20260219-v1-0-2b4d74e309d1@gmail.com
