[PATCH] kbuild: fix modpost when used with O=
From: Sam Ravnborg <sam@ravnborg.org> modpost or to be more specific sumversion.c was not behaving correct when used with O= and MODULE_VERSION was used. Previously it failed to use local .h when calculation the md-sum in case of a O= build. The following patch introduces the following: - A generic get_next_line() - Check that the topmost part of the directory matches - Using strrch when checking for file with suffix .o - Use NOFAIL for allocations in sumversion - Avoid memory leak in new_module The generic get_next_line will pay off when Andreas implmentation of storing symbol addresses in a seperate file is introduced.
