    lib/vsprintf: allow printing upper case GUIDs · 3bad256f
    Heinrich Schuchardt authored
    In the UEFI context GUIDs are expected to be rendered in upper case.
    
    The patch uses the formerly unused bit 1 of the parameter str_format
    of function uuid_bin_to_str() to indicate if we need upper or lower case
    output.
    
    Function uuid_string() in vsprint.c is adjusted to correctly set the bit
    depending on the print format code.

    %pUB: 01020304-0506-0708-090A-0B0C0D0E0F10
    %pUl: 04030201-0605-0807-090a-0b0c0d0e0f10
    %pUL: 04030201-0605-0807-090A-0B0C0D0E0F10
    
    Up to this point only a diagnostic message in mount_ubifs() using '%pUB' is
    concerned by the change. Further patches are needed to adjust the UEFI
    subsystem.
    
    A unit test is provided inside the ut_print command.
