[ Upstream commit 1264c1e0cfe55e2d6c35e869244093195529af37 ]

This patch causes a regression betwen Kernel 5.7 and 5.8 at wlcore:
with it applied, WiFi stops working, and the Kernel starts printing
this message every second:

wl1251: fix always return 0 error

2020-08-19T06:26:53+00:00

[ Upstream commit 20e6421344b5bc2f97b8e2db47b6994368417904 ]

wl1251_event_ps_report() should not always return 0 because
wl1251_ps_set_mode() may fail. Change it to return 'ret'.

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/'

wlcore: fix runtime pm imbalance in wlcore_irq_locked

2020-05-29T17:38:15+00:00

When wlcore_fw_status() returns an error code, a pairing
runtime PM usage counter decrement is needed to keep the
counter balanced. It's the same for all error paths after
wlcore_fw_status().

wlcore: fix runtime pm imbalance in wlcore_regdomain_config

2020-05-29T17:31:59+00:00

pm_runtime_get_sync() increments the runtime PM usage counter even
the call returns an error code. Thus a pairing decrement is needed
on the error handling path to keep the counter balanced.

wlcore: fix runtime pm imbalance in wl1271_tx_work

2020-05-29T17:31:03+00:00

There are two error handling paths in this functon. When
wlcore_tx_work_locked() returns an error code, we should
decrease the runtime PM usage counter the same way as the
error handling path beginning from pm_runtime_get_sync().
