Subject: [PATCH] qed: Avoid constant logical operation warning in qed_vf_pf_acquire
Date: Mon, 24 Sep 2018 15:17:03 -0700 [thread overview]
Message-ID: <20180924221703.26454-1-natechancellor@gmail.com> (raw)
Clang warns when a constant is used in a boolean context as it thinks a
bitwise operation may have been intended.
drivers/net/ethernet/qlogic/qed/qed_vf.c:415:27: warning: use of logical
'&&' with constant operand [-Wconstant-logical-operand]
if (!p_iov->b_pre_fp_hsi &&
^
drivers/net/ethernet/qlogic/qed/qed_vf.c:415:27: note: use '&' for a
bitwise operation
if (!p_iov->b_pre_fp_hsi &&
^~
&
drivers/net/ethernet/qlogic/qed/qed_vf.c:415:27: note: remove constant
to silence this warning
if (!p_iov->b_pre_fp_hsi &&
~^~
1 warning generated.
This has been here since commit 1fe614d10f45 ("qed: Relax VF firmware
requirements") and I am not entirely sure why since 0 isn't a special
case. Just remove the statement causing Clang to warn since it isn't
required.
