From mboxrd@z Thu Jan 1 00:00:00 1970 From: Arnd Bergmann Subject: [PATCH 1/2] phy: rockchip-inno-usb2: fix uninitialized tmout variable Date: Wed, 16 Nov 2016 15:22:38 +0100 Message-ID: <20161116142259.2123506-1-arnd@arndb.de> Return-path: Sender: linux-kernel-owner@vger.kernel.org To: Kishon Vijay Abraham I Cc: Arnd Bergmann , Heiko Stuebner , William Wu , Douglas Anderson , Frank Wang , linux-kernel@vger.kernel.org, linux-arm-kernel@lists.infradead.org, linux-rockchip@lists.infradead.org List-Id: linux-rockchip.vger.kernel.org The newly added OTG support has an obvious uninitialized variable access that gcc warns about: drivers/phy/phy-rockchip-inno-usb2.c: In function 'rockchip_chg_detect_work': drivers/phy/phy-rockchip-inno-usb2.c:717:7: error: 'tmout' may be used uninitialized in this function [-Werror=maybe-uninitialized] This replaces the use of the uninitialized variable with what the value was in the previous USB_CHG_STATE_WAIT_FOR_DCD state.
