From 2283a117f65650352f2a9fd6b9af4cdbf5478d14 Mon Sep 17 00:00:00 2001 From: Randy Dunlap Date: Thu, 7 Jul 2005 15:39:26 -0700 Subject: [PATCH] scripts/kernel-doc: don't use uninitialized SRCTREE Current kernel-doc (perl) script generates this warning: Use of uninitialized value in concatenation (.) or string at scripts/kernel-doc line 1668. So explicitly check for SRCTREE in the ENV before using it, and then if it is set, append a '/' to the end of it, otherwise the SRCTREE + filename can (will) be missing the intermediate '/'.
