Subject: [PATCH 0/5] iio: proximity: hx9023s: firmware property, safety
 fixes, and ACPI support

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.
 - Adding ACPI device ID support to enable hx9023s on ACPI-based platforms.

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
