From 9b0fa60d9be0a82bc9e49bdd2dcacdfe4d1d5192 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Thu, 3 Apr 2014 14:49:18 -0700 Subject: [PATCH] checkpatch: add test for char * arrays that could be static const static const char* arrays create smaller text as each function call does not have to populate the array. Emit a warning when char *arrays aren't static const and the array is not apparently global by being declared in the first column.
