Commit Message

Laurent Pinchart Oct. 27, 2021, 11 p.m. UTC 
When the IPU3 pipeline handler is disabled, the corresponding IPA module
isn't compiled, which results in the meson ipu3_ipa_sources variable to
be undefined. The variable is used unconditionally as part of the
Doxygen inputs, so Meson complains at configuration time that it is
undefined.

Fix it by including the IPU3 IPA documentation in the Doxygen build only
when the IPU3 pipeline handler is enabled.

Fixes: 45dd51988952 ("Documentation: Include IPU3 in Doxygen build")
