Subject: usb: dwc3: exynos/omap: Change platform device IDs for no_op_xceive to AUTO
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b0e45ddb96d5a972a8b76354f036b90549ae85b3;p=openwrt%2Fstaging%2Fblogic.git

usb: dwc3: exynos/omap: Change platform device IDs for no_op_xceive to AUTO

Multiple dwc3 probe calls try to allocate no_op_xceive platform
device. Having static IDs for these will throw sysfs error -EEXIST.
Changing these static platform device IDs to AUTO to enable
multiple dwc3 controller support on a SoC.
