That patch seems to completely negate the purpose of the existing
efi_locate_device() function. What is it that you are trying to achieve?
My understanding is that efi_locate_device is called with the system
handle from drivers/net/efi/snponly.c:82 to find the device that
supports the Simple Network Protocol.
Not quite. It's supposed to find the closest SNP-supporting parent of
the specified device. The idea is not just to find any SNP, but to find
the SNP from which iPXE itself was loaded. This makes a difference if
the system has more than one SNP device.
