From 3354957a4f8b9bb4b43625232acdf0626851c82f Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Mon, 24 May 2010 14:33:29 -0700 Subject: checkpatch: add check for too short Kconfig descriptions I've seen various new Kconfigs with rather unhelpful one liner descriptions. Add a Kconfig warning for a minimum length of the Kconfig help section. Right now I arbitarily chose 4. The exact value can be debated.
