Trying to copy into the string fields with strncpy() gives a warning from
gcc. Both fields are part of a packed HDMI header and do not require a
terminating \0 character.
../drivers/video/hdmi.c: In function 'hdmi_spd_infoframe_init':
../drivers/video/hdmi.c:230:2: warning: 'strncpy' specified bound 8 equals destination size [-Wstringop-truncation]
230 | strncpy(frame->vendor, vendor, sizeof(frame->vendor));

../drivers/video/hdmi.c:231:2: warning: 'strncpy' specified bound 16 equals destination size [-Wstringop-truncation]
231 | strncpy(frame->product, product, sizeof(frame->product));
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Just use memcpy() instead.
