* usb: mtu3: get optional clock by devm_clk_get_optional()Chunfeng Yun2019-04-191-16/+3Star
| | | | | | | | | | | | Use devm_clk_get_optional() to get optional clock instead of optional_clk_get() which uses devm_clk_get() to get clock and checks for -EPROBE_DEFER but not -ENOENT as devm_clk_get_optional() does, in fact, only ignoring -ENOENT will cover more errors, so the replacement doesn't change original purpose.

The root cause is as the following: When the xHCI driver set PORT_POWER of the OTG port, and if both IDPIN and VBUS_VALID are high at the same time, the MTU3 controller will set SESSION and pull up DP, so the Win7 can detect existence of USB device, but if the mtu3 driver can't switch to device mode during the debounce time, the Win7 can not enumerate it.

| * USB: add SPDX identifiers to all remaining files in drivers/usb/Greg Kroah-Hartman2017-11-0411-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.
