Description of problem:

If we install RHEL7.6 or RHEL7.7 on a VM which have Cirrus Logic graphics, 

 00:02.0 VGA compatible controller [0300]: Cirrus Logic GD 5446 [1013:00b8] (prog-if 00 [VGA controller])

 System Information
        Manufacturer: Red Hat
        Product Name: KVM
        Version: RHEL 7.0.0 PC

We are getting following errors in the /var/log/messages logs:

$ less /var/log/messages|grep wayland
Jul 29 23:32:35 HOSTNAME systemd-udevd: failed to execute '/usr/libexec/gdm-disable-wayland' '/usr/libexec/gdm-disable-wayland': No such file or directory

There is no visible impact of the error message.

Version-Release number of selected component (if applicable):
gdm-3.28.2-16.el7.x86_64(RHEL7.7)
gdm-3.28.2-12.el7_6.2.x86_64(RHEL7.6)

How reproducible:
Always

Steps to Reproduce:
1. Install RHEL7.6 or 7.7 on a VM. Make sure to use Cirrus Logic graphics on the system.
2. Start the system in GUI mode, Switch runlevel from textmode to Gui mode.


Actual results:
"/usr/libexec/gdm-disable-wayland" missing and getting above mentioned message in the logs.

Expected results:
Add the missing file so that there is no error message.

Additional info:

The error appears in the log due to the following udev rule:

RHEL7.7 ~]# vim /usr/lib/udev/rules.d/61-gdm.rules
# disable Wayland on Cirrus chipsets
ATTR{vendor}=="0x1013", ATTR{device}=="0x00b8", ATTR{subsystem_vendor}=="0x1af4", ATTR{subsystem_device}=="0x1100", RUN+="/usr/libexec/gdm-disable-wayland"

The above mentioned udev rule is added by gdm:

RHEL7.7 ~]# rpm -qf /usr/lib/udev/rules.d/61-gdm.rules 
gdm-3.28.2-16.el7.x86_64

But the GDM package available in RHEL 7.6 or RHEL 7.7 does not provide "/usr/libexec/gdm-disable-wayland". 

The "/usr/libexec/gdm-disable-wayland" file is provided by the gdm package in Fedora, but not in RHEL.

Fedora30 ~]$ rpm -qf /usr/libexec/gdm-disable-wayland
gdm-3.32.0-3.fc30.x86_64
