fixed the svn. thanks for tips. and applied the patched, make and make install worked fine: # patch < /home/krmx/nxprtc.patch Hmm... Looks like a unified diff to me... The text leading up to this was: -------------------------- |--- sys/dev/iicbus/nxprtc.c 2019/05/23 18:24:27 348184 |+++ sys/dev/iicbus/nxprtc.c 2019/07/15 21:47:40 350016 -------------------------- Patching file sys/dev/iicbus/nxprtc.c using Plan A...
