From f6aafac184a3e46e919769dd4faa8bf0dc436534 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 14 Mar 2017 13:18:45 +0100 Subject: IB/qib: fix false-postive maybe-uninitialized warning aarch64-linux-gcc-7 complains about code it doesn't fully understand: drivers/infiniband/hw/qib/qib_iba7322.c: In function 'qib_7322_txchk_change': include/asm-generic/bitops/non-atomic.h:105:35: error: 'shadow' may be used uninitialized in this function [-Werror=maybe-uninitialized] The code is right, and despite trying hard, I could not come up with a version that I liked better than just adding a fake initialization here to shut up the warning.
