Fails to build with Qt 6.9(.1): error: no match for ‘operator==’ (operand types are ‘Flipper::Zero::HardwareInfo’ and ‘Flipper::Zero::HardwareInfo’)

[thican]

Describe the bug
Trying to build the qFlipper GUI with Qt 6.9.1 following build instructions from README.md, it fails during the make step.

To Reproduce

1. Update your system or build environment with Qt 6.9.1;
2. Query instructions for "Standalone build" on README.md;
3. execute the make step;
4. See error in build log or in your terminal.

Expected behavior
Build process should build without issues, at least as it was with Qt 6.8 and prior.

Actual behavior

It fails with the following error from GCC

Additional troubleshooting

1. Does the issue persist if you try multiple times?

• Yes it does.

2. Does reconnecting/rebooting Flipper solve it?

• Unrelated.

The report must also include at least one of the following:

1. A FULL LOG of this application run. (see below).

• Non applicable.

2. A screenshot of the application window (if it is a graphical issue).

• Non applicable.
