Parse the HID_FIRMWARE_VERSION uevent property to populate release_number for all HID devices. This provides device version information for I2C, Bluetooth, SPI, and virtual HID devices.

For USB devices, the existing bcdDevice lookup from sysfs still takes precedence, maintaining backward compatibility.

The HID_FIRMWARE_VERSION property is being added to the Linux kernel (patch series submitted to linux-input@vger.kernel.org). On kernels without this property, release_number will remain 0 for non-USB devices, preserving existing behavior.

Also added here, which looks like it's going into 7.1 by @superm1: https://git.kernel.org/pub/scm/linux/kernel/git/hid/hid.git/commit/?h=for-7.1/lenovo-v2&id=6ca9029c823b7853e980585e757343e0e84227cd

I don't believe I have a way to properly check/test this, but quick googling shows that this is perfectly fine.
Thanks!
