2023-02-22clk: qcom: Revert sync_state based clk_disable_unusedBjorn Andersson
Revert the postponement of clk_disable_unused() for clock providers that implement sync_state, and the change to drivers implementing this, until agreement on the implementation has been reached.

2023-02-22backlight: pwm_bl: Don't rely on a disabled PWM emiting inactive stateUwe Kleine-König
Most but not all PWMs drive the PWM pin to its inactive state when disabled. However if there is no enable_gpio and no regulator the PWM must drive the inactive state to actually disable the backlight. So keep the PWM on in this case. Note that to determine if there is a regulator some effort is required because it might happen that there isn't actually one but the regulator core gave us a dummy. (A nice side effect is that this makes the regulator actually optional even on fully constrained systems.) This fixes backlight disabling e.g. on i.MX6 when an inverted PWM is used. Hint for the future: If this change results in a regression, the bug is in the lowlevel PWM driver.

2023-02-22backlight: pwm_bl: Configure pwm only once per backlight toggleUwe Kleine-König
When the function pwm_backlight_update_status() was called with brightness > 0, pwm_get_state() was called twice (once directly and once in compute_duty_cycle). Also pwm_apply_state() was called twice (once in pwm_backlight_power_on() and once directly). Optimize this to do both calls only once. Note that with this affects the order of regulator and PWM setup. It's not expected to have a relevant effect on hardware. The rationale for this is that the regulator (and the GPIO) are reasonable to switch in pwm_backlight_power_on()/pwm_backlight_power_off() but the PWM has nothing to do with power. (The post_pwm_on_delay and pwm_off_delay are still there though.)

2023-02-22wifi: ath11k: allow system suspend to survive ath11kLen Brown
When ath11k runs into internal errors upon suspend, it returns an error code to pci_pm_suspend, which aborts the entire system suspend. The driver should not abort system suspend, but should keep its internal errors to itself, and allow the system to suspend. Otherwise, a user can suspend a laptop by closing the lid and sealing it into a case, assuming that is will suspend, rather than heating up and draining the battery when in transit. In practice, the ath11k device seems to have plenty of transient errors, and subsequent suspend cycles after this failure often succeed. https://bugzilla.kernel.org/show_bug.cgi?id=216968 Fixes: d1b0c33850d29 ("ath11k: implement suspend for QCA6390 PCI devices") Signed-off-by: Len Brown <len.brown@intel.com> Cc: stable@vger.kernel.org Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://lore.kernel.org/r/20230201183201.14431-1-len.brown@intel.com

Probability of hitting this error path is low AFAICS (xt_register_table can only return ENOMEM here, as it is not replacing anything, as we are creating new netns, and it is hard to imagine that all previous allocations succeeded and after that one in xt_register_table failed).
