Subject: [4.4-stable 07/22] usb: phy: msm add regulator dependency
Date: Tue, 20 Feb 2018 12:54:54 +0100 [thread overview]
Message-ID: <20180220115527.1806578-8-arnd@arndb.de> (raw)
In-Reply-To: <20180220115527.1806578-1-arnd@arndb.de>
On linux-4.4 and linux-4.9 we get a warning about an array that is
never initialized when CONFIG_REGULATOR is disabled:
drivers/usb/phy/phy-msm-usb.c: In function 'msm_otg_probe':
drivers/usb/phy/phy-msm-usb.c:1911:14: error: 'regs[0].consumer' may be used uninitialized in this function [-Werror=maybe-uninitialized]
motg->vddcx = regs[0].consumer;
~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~
drivers/usb/phy/phy-msm-usb.c:1912:14: error: 'regs[1].consumer' may be used uninitialized in this function [-Werror=maybe-uninitialized]
motg->v3p3 = regs[1].consumer;
~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~
drivers/usb/phy/phy-msm-usb.c:1913:14: error: 'regs[2].consumer' may be used uninitialized in this function [-Werror=maybe-uninitialized]
motg->v1p8 = regs[2].consumer;
This adds a Kconfig dependency for it. In newer kernels, the driver no
longer exists, so this is only needed for stable kernels.
