If anyone has any objections, please let me know. ------------------ From: Arnd Bergmann 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.
