USB: iowarrior: fix up report size handling for some devices

2020-08-11T13:48:06+00:00

commit 17a82716587e9d7c3b246a789add490b2b5dcab6 upstream.

In previous patches that added support for new iowarrior devices, the
handling of the report size was not done correct.

Fix that up and update the copyright date for the driver

Reworked from an original patch written by Christoph Jung.

Fixes: bab5417f5f01 ("USB: misc: iowarrior: add support for the 100 device")
Fixes: 5f6f8da2d7b5 ("USB: misc: iowarrior: add support for the 28 and 28L devices")
Fixes: 461d8deb26a7 ("USB: misc: iowarrior: add support for 2 OEMed devices")

treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21+00:00

Since commit 84af7a6194e4 ("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/'

USB: sisusbvga: Change port variable from signed to unsigned

2020-04-23T13:26:17+00:00

Change a bunch of arguments of wrapper functions which pass signed
integer to an unsigned integer which might cause undefined behaviors
when sign integer overflow.

USB: misc: Use the correct style for SPDX License Identifier

2020-04-16T12:32:47+00:00

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).

Changes made by using a script provided by Joe Perches here:

usb: usb251xb: fix regulator probe and error handling

2020-03-04T09:56:26+00:00

Commit 4d7201cda226 ("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.

USB: misc: iowarrior: add support for the 100 device

2020-02-17T09:44:43+00:00

Add a new device id for the 100 devie.  It has 4 interfaces like the 28
and 28L devices but a larger endpoint so more I/O pins.
