From b9fadaa3757fc47c19b7a6b994f34fd8a1dada5e Mon Sep 17 00:00:00 2001 From: Andrzej Ostruszka Date: Thu, 7 Nov 2019 16:03:15 +0100 Subject: [PATCH] e1000: clean LTO warnings During LTO build compiler reports some 'false positive' warnings about variables being possibly used uninitialized. This patch silences these warnings. Exemplary compiler warning to suppress (with LTO enabled): error: 'link' may be used uninitialized in this function [-Werror=maybe-uninitialized] if (link) { Signed-off-by: Andrzej Ostruszka Approved by: imp Obtained from: DPDK (46136031f19107f4e9b6b3a952cb7f57877a7f0f) MFC after: 1 week (cherry picked from commit 089cdb3990f47be3cd34d1a57567a2e89c917929) --- sys/dev/e1000/e1000_82543.c | 2 +- sys/dev/e1000/e1000_ich8lan.c | 2 +- sys/dev/e1000/e1000_phy.c | 2 +- 3 files changed, 3 insertions(+), 3 deletions(-) diff --git a/sys/dev/e1000/e1000_82543.c b/sys/dev/e1000/e1000_82543.c index 42c4726fa8c..49049b8646c 100644 --- a/sys/dev/e1000/e1000_82543.c +++ b/sys/dev/e1000/e1000_82543.c @@ -1062,7 +1062,7 @@ static s32 e1000_setup_copper_link_82543(struct e1000_hw *hw) { u32 ctrl; s32 ret_val; - bool link; + bool link = true; DEBUGFUNC("e1000_setup_copper_link_82543"); diff --git a/sys/dev/e1000/e1000_ich8lan.c b/sys/dev/e1000/e1000_ich8lan.c index 8ca0fb39280..635be03f290 100644 --- a/sys/dev/e1000/e1000_ich8lan.c +++ b/sys/dev/e1000/e1000_ich8lan.c @@ -5620,7 +5620,7 @@ void e1000_igp3_phy_powerdown_workaround_ich8lan(struct e1000_hw *hw) void e1000_gig_downshift_workaround_ich8lan(struct e1000_hw *hw) { s32 ret_val; - u16 reg_data; + u16 reg_data = 0; DEBUGFUNC("e1000_gig_downshift_workaround_ich8lan"); diff --git a/sys/dev/e1000/e1000_phy.c b/sys/dev/e1000/e1000_phy.c index d84b6120dd3..2eae3acbe50 100644 --- a/sys/dev/e1000/e1000_phy.c +++ b/sys/dev/e1000/e1000_phy.c @@ -1695,7 +1695,7 @@ s32 e1000_copper_link_autoneg(struct e1000_hw *hw) s32 e1000_setup_copper_link_generic(struct e1000_hw *hw) { s32 ret_val; - bool link; + bool link = true; DEBUGFUNC("e1000_setup_copper_link_generic");
