Masahiro Yamada a7f7f6248d treewide: replace '---help---' in Kconfig files with 'help' 
Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.

This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.

There are a variety of indentation styles found.

  a) 4 spaces + '---help---'
  b) 7 spaces + '---help---'
  c) 8 spaces + '---help---'
  d) 1 space + 1 tab + '---help---'
  e) 1 tab + '---help---'    (correct indentation)
  f) 1 tab + 1 space + '---help---'
  g) 1 tab + 2 spaces + '---help---'

In order to convert all of them to 1 tab + 'help', I ran the
following commend:

  $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

This patch corrects the SPDX License Identifier style in
header files related to USB Miscellaneous drivers.
For C header files Documentation/process/license-rules.rst
mandates C-like comments (opposed to C source files where
C++ style should be used).

Marco Felsch f06947f275 usb: usb251xb: fix regulator probe and error handling 
Commit 4d7201cda2 ("usb: usb251xb: add vdd supply support") didn't
covered the non-DT use-case and so the regualtor_enable() call during
probe will fail on those platforms. Also the commit didn't handled the
error case correctly.

Move devm_regulator_get() out of usb251xb_get_ofdata() to address the
1st issue. This can be done without worries because devm_regulator_get()
handles the non-DT use-case too. Add devm_add_action_or_reset() to
address the 2nd bug.

Linus Walleij 51d22e855e usb: usb3503: Convert to use GPIO descriptors 
This converts the USB3503 to pick GPIO descriptors from the
device tree instead of iteratively picking out GPIO number
references and then referencing these from the global GPIO
numberspace.

The USB3503 is only used from device tree among the in-tree
platforms. If board files would still desire to use it they can
provide machine descriptor tables.

Make sure to preserve semantics such as the reset delay
introduced by Stefan.
