5.4.102 backported a lot of stuff that our WireGuard backport already did, in addition to other patches we had, so those patches were removed from that part of the series. In the process other patches were refreshed or reworked to account for upstream changes. This commit involved `update_kernel.sh -v -u 5.4`.

Subject: watchdog: qcom-wdt: disable pretimeout on timer platform
|
|
|
|
Some platform like ipq806x doesn't support pretimeout and define
|
|
some interrupts used by qcom,msm-timer. Change the driver to check
|
|
and use pretimeout only on qcom,kpss-wdt as it's the only platform
|
|
that actually supports it.
