When a device path protocol is installed write the device path to the console in debug mode.
For printing the new macro EFI_PRINT is used, which can be reused for future diagnostic output.
Remove unused EFI_PRINT_GUID macro
Signed-off-by: Heinrich Schuchardt xypron.glpk@gmx.de --- v3 Avoid memory leak. Use printf("%pD") for device path output. v2 Remove unused EFI_PRINT_GUID macro. Use new macro EFI_PRINT to output device path. --- include/efi_loader.h | 7 ++++--- lib/efi_loader/efi_boottime.c | 2 ++ 2 files changed, 6 insertions(+), 3 deletions(-)
