[gPXE-devel] [PATCH] Build breakage caused by new pcnet32 driver

[Geoff Lywood]

Using gcc 4.1.2, I get the following error when running 'make bin/pcnet32.rom':

  [BUILD] bin/pcnet32.o
cc1: warnings being treated as errors
drivers/net/pcnet32.c: In function 'pcnet32_probe':
drivers/net/pcnet32.c:516: warning: 'phycount' may be used uninitialized in this function
make: *** [bin/pcnet32.o] Error 1

Here is a patch to fix the problem.
