From 16b9d870a0f19f6c1061927a623d9c51c09f2bed Mon Sep 17 00:00:00 2001 From: Finn Thain Date: Thu, 29 May 2014 00:43:43 +1000 Subject: [PATCH] scsi/NCR5380: dprintk macro This is the delta between the two submissions: [PATCH 00/12] scsi/NCR5380: fix debugging macros and #include structure and [PATCH v2 00/12] scsi/NCR5380: fix debugging macros and #include structure The macro definition changes were discussed on the mailing list during review. The idea is to get the compiler to check the parameters of disabled printk() calls so that the debugging code doesn't rot again.
