From bd70134396622ea50b14e34dae0810879884d553 Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Wed, 29 May 2013 13:18:56 +0100 Subject: [PATCH] improve modalias building For one, there's no point in the respective pieces to be rebuilt unconditionally on each and every rebuild. Second there's no need to invent a custom rule for generating the .s file from the .c source - we can simply use the generic rule here. And finally, $(obj) should be used to refer to files in the build tree (rather than spelling out the subdirectory).
