[Qemu-devel] [PULL 02/28] checkpatch: Eliminate false positive in case o


From: Paolo Bonzini
Subject: [Qemu-devel] [PULL 02/28] checkpatch: Eliminate false positive in case of space before square bracket in a definition
Date: Tue, 16 Feb 2016 17:34:20 +0100

From: Leonid Bloch <address@hidden>

Now, macro definition such as "#define abc(x) [x] = y" should pass
without an error.
