usb: Use fallthrough pseudo-keyword

2020-07-10T06:55:17+00:00

Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.

media: USB: cdc-acm: blacklist IR Droid / IR Toy device

2020-06-23T13:07:40+00:00

The IR Droid / IR Toy device used custom protocol over serial
line, so it is presenting itself as CDC ACM device.

Now that we have proper in-kernel driver for it we need to black-list the
device in cdc-acm driver.

cdc-acm: Add DISABLE_ECHO quirk for Microchip/SMSC chip

2020-06-18T08:42:52+00:00

USB_DEVICE(0x0424, 0x274e) can send data before cdc_acm is ready,
causing garbage chars on the TTY causing stray input to the shell
and/or login prompt.

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/'

CDC-ACM: heed quirk also in error handling

2020-05-27T08:25:40+00:00

If buffers are iterated over in the error case, the lower limits
for quirky devices must be heeded.

usblp: poison URBs upon disconnect

2020-05-13T12:20:00+00:00

syzkaller reported an URB that should have been killed to be active.
We do not understand it, but this should fix the issue if it is real.
