I stumbled over this warning last week, which showed up after I had removed an incorrect patch from my randconfig build setup: drivers/usb/phy/phy-msm-usb.c: In function 'msm_otg_probe': drivers/usb/phy/phy-msm-usb.c:1735:14: 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:1736:14: 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:1737:14: error: 'regs[2].consumer' may be used uninitialized in this function [-Werror=maybe-uninitialized] motg->v1p8 = regs[2].consumer; ~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~ Having already fixed the same problem in the phy-qcom-8x16-usb.c driver before, I tried to do the same thing here, but it turned out to be somewhat different, and I ended up running into several unrelated issues in the driver that I now try to fix up. The series is not tested beyond verifying that it no longer causes randconfig warnings, and some patches are not entirely obvious. In particular the ehci-msm and chipidea changes are probably a good idea, but they actually change the behavior of the drivers in a way that I cannot verify through inspection alone. The last patch in the series probably requires some changes to the devicetree files to go along with it. Please have a look and test this, provided the patches make sense conceptually.
