Functions changes summary: 0 Removed, 1 Changed, 3 Added functions
Variables changes summary: 0 Removed, 0 Changed, 0 Added variable

3 Added functions:

  'function FILE* efi_get_logfile()'    {efi_get_logfile@@LIBEFIVAR_1.36}
  'function int efi_get_verbose()'    {efi_get_verbose@@LIBEFIVAR_1.36}
  'function void efi_set_verbose(int, FILE*)'    {efi_set_verbose@@LIBEFIVAR_1.36}

1 function with some indirect sub-type change:

  [C]'function ssize_t efidp_make_acpi_hid_ex(uint8_t*, ssize_t, uint32_t, uint32_t, uint32_t, char*, char*, char*)' at <built-in>:263:1 has some indirect sub-type changes:
    parameter 6 of type 'char*' changed:
      in pointed to type 'char':
        entity changed from 'char' to 'const char'
        type size hasn't changed
    parameter 7 of type 'char*' changed:
      in pointed to type 'char':
        entity changed from 'char' to 'const char'
        type size hasn't changed
    parameter 8 of type 'char*' changed:
      in pointed to type 'char':
        entity changed from 'char' to 'const char'
        type size hasn't changed

The 3 added functions are as they should be.  The
efidp_make_acpi_hid_ex() changes are all from making arguments "const"
that weren't before, and that's fine as well.
