Bugzilla 40012: PIO_UNIMAP bug: error updating Unicode-to-font map
https://bugzilla.kernel.org/show_bug.cgi?id=40012
The unicode font map for the virtual console is a 32x32x64 table which
allocates rows dynamically as entries are added. The unicode value
increases sequentially and should count all entries even in empty
rows. The defect is when copying the unicode font map in con_set_unimap(),
the unicode value is not incremented properly. The wrong unicode value
is entered in the new font map.
