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/'

net: dp83869: Reset return variable if PHY strap is read

2020-06-06T22:53:44+00:00

When the PHY's strap register is read to determine if lane swapping is
needed the phy_read_mmd returns the value back into the ret variable.

If the call to read the strap fails the failed value is returned.  If
the call to read the strap is successful then ret is possibly set to a
non-zero positive number. Without reseting the ret value to 0 this will
cause the parse DT function to return a failure.

net: phy: mscc: fix Serdes configuration in vsc8584_config_init

2020-06-05T20:16:13+00:00

When converting the MSCC PHY driver to shared PHY packages, the Serdes
configuration in vsc8584_config_init was modified to use 'base_addr'
instead of 'base' as the port number. But 'base_addr' isn't equal to
'addr' for all PHYs inside the package, which leads to the Serdes still
being enabled on those ports. This patch fixes it.

net: mdiobus: Disable preemption upon u64_stats update

2020-06-04T22:50:42+00:00

The u64_stats mechanism uses sequence counters to protect against 64-bit
values tearing on 32-bit architectures. Updating u64_stats is thus a
sequence counter write side critical section where preemption must be
disabled.

For mdiobus_stats_acct(), disable preemption upon the u64_stats update.
It is called from process context through mdiobus_read() and
mdiobus_write().

net: phy: fixed_phy: Remove unused seqcount

2020-06-04T22:50:42+00:00

Commit bf7afb29d545 ("phy: improve safety of fixed-phy MII register
reading") protected the fixed PHY status with a sequence counter.

Two years later, commit d2b977939b18 ("net: phy: fixed-phy: remove
fixed_phy_update_state()") removed the sequence counter's write side
critical section -- neutralizing its read side retry loop.

Remove the unused seqcount.
