Subject: video: hdmi: Change return type of hdmi_avi_infoframe_init() to void
Git-commit: 5ee0caf161a9a21b9410b29f3cae8e1e98d1b100
Patch-mainline: v5.7-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
The hdmi_avi_infoframe_init() never needs to return an error, change its
return type to void.
