that comes from the previous patch which adds utf16 support.. I think
that should be the only conflicting hunk, the later bits are far
enough away from the utf16 related hunks.

I was not able to apply the patch to v2017.09-rc1 nor to git HEAD.

Applying: vsprintf.c: add GUID printing
error: patch failed: lib/vsprintf.c:18
error: lib/vsprintf.c: patch does not apply

This is my lib/vsprintf.c:
 14 #include 
 15 #include 
 16 #include 
 17 #include 
 18
 19 #include 
 20
 21 #include 

There is no line with #include .

[U-Boot] [PATCH] vsprintf.c: add GUID printing

2017-08-06 Thread Rob Clark 
This works (roughly) the same way as linux's, but we currently always
print lower-case (ie. we just keep %pUB and %pUL for compat with linux),
mostly just because that is what uuid_bin_to_str() supports.

  %pUb:   01020304-0506-0708-090a-0b0c0d0e0f10
  %pUl:   04030201-0605-0807-090a-0b0c0d0e0f10

It will be used by a later efi_loader paths for efi variables and for
device-path-to-text protocol, and also quite useful for debug prints
of protocol GUIDs.

This replaces "efi_loader: add guidstr helper" in my "enough UEFI for
standard distro boot" patchset, and could also replace Heinrich's
"efi_loader: write protocol GUID in OpenProtocol" with a single one-
line debug() print.
