Subject: efi_loader: use u16* for file name
X-Git-Tag: v2019.04-rc2~13^2~25
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=c82f8f600a34d540f95a04e9cb3c49a9e6b3ae83;p=oweals%2Fu-boot.git

efi_loader: use u16* for file name

UTF-16 strings in our code should all be u16 *. Fix an inconsistency for
file names which may lead to a warning for printf("%ls", ).
