Hi Christoph,

Looks like I misunderstood your comment from https://patchwork.kernel.org/patch/11309223/:

The "le16_to_cpu(ptes[i].partition_name[label_count])" call is the 
full implementation of the "efi_char_from_cpu" logic. Do you want 
to encapsulate "utf16_le_to_7bit_string" logic entirely like in
the attached version?

Regards,
Nikolai
