[PATCH AUTOSEL 5.10 1/4] pinctrl: meson: define the pull up/down resistor value as 60 kOhm
From: Martin Blumenstingl martin.blumenstingl@googlemail.com
[ Upstream commit e56088a13708757da68ad035269d69b93ac8c389 ]
The public datasheets of the following Amlogic SoCs describe a typical resistor value for the built-in pull up/down resistor: - Meson8/8b/8m2: not documented - GXBB (S905): 60 kOhm - GXL (S905X): 60 kOhm - GXM (S912): 60 kOhm - G12B (S922X): 60 kOhm - SM1 (S905D3): 60 kOhm
The public G12B and SM1 datasheets additionally state min and max values: - min value: 50 kOhm for both, pull-up and pull-down - max value for the pull-up: 70 kOhm - max value for the pull-down: 130 kOhm
Use 60 kOhm in the pinctrl-meson driver as well so it's shown in the debugfs output. It may not be accurate for Meson8/8b/8m2 but in reality 60 kOhm is closer to the actual value than 1 Ohm.

HP Spectre x360 15-df1xxx with SSID 13c:863e requires similar workarounds that were applied to another HP Spectre x360 models; it has a mute LED only, no micmute LEDs, and needs the speaker GPIO seup.

queue->state_change is set as part of nvmet_tcp_set_queue_sock(), but if the TCP connection isn't established when nvmet_tcp_set_queue_sock() is called then queue->state_change isn't set and sock->sk->sk_state_change isn't replaced.
As such we don't need to restore sock->sk->sk_state_change if queue->state_change is NULL.
This avoids NULL pointer dereferences such as this:
