SUMMARY
On Plasma 6.1.4, the kde-plasma/plasma-desktop (with the package name, you already should know I use Gentoo) package fails to build with Clang 19

STEPS TO REPRODUCE
1. Attempt to build =kde-plasma/plasma-desktop-6.1.4
2. Watch it fail
3. Wallow in misery

OBSERVED RESULT
Build failed due to a malformed header file

EXPECTED RESULT
A successful build, as I had built previous versions of Plasma.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Gentoo Linux 2.15 running on Linux 6.10.3-linux-cachyos
KDE Plasma Version: 6.1.4
KDE Frameworks Version: 6.5.0
Qt Version: 6.7.2

ADDITIONAL INFORMATION

I'm using Clang 19.1.0_rc2, so that could be the issue.

kcms/libkwindevices: use function value instead of function

Prop<T> p.value is a function. We should call set on its return value,
instead of on the function pointer.
