Problem/Motivation

PHP 7.4 causes these notices in watchdog:

Notice: Trying to access array offset on value of type null in linked_field_field_attach_view_alter() (line 360 of /var/www/html/docroot/sites/all/modules/contrib/linked_field/linked_field.module).
Notice: Trying to access array offset on value of type null in linked_field_field_attach_view_alter() (line 363 of /var/www/html/docroot/sites/all/modules/contrib/linked_field/linked_field.module).

This is an issue for Display Suite fields, which are handled just a few lines later.

Steps to reproduce

Use PHP 7.4 to serve a site, and view pages with Display Suite fields.

Proposed resolution

A better solution may be move the Display Suite field handling up as part of the if/else chain, however that may be too much change. Proposed patch will just test values before setting.

Remaining tasks

User interface changes

None.

API changes

None.

Data model changes

None.
