Move configuration normally done on probe to lenovo_features_set_cptkbd(), then recycle this for use on reset_resume. Without, the keyboard and driver would end up in an inconsistent state, breaking middle-button scrolling amongst other problems, and twiddling sysfs values wouldn't help as the middle-button mode won't be set until the driver is reloaded.

In case a signal (SIGINT, SIGTERM, or SIGHUP) is received, the running selftest is aborted by ctrlc_handler() which then unmounts resctrl fs before exiting. The current section between signal_handler_register() and signal_handler_unregister(), however, does not cover the entire duration when resctrl FS is mounted. Move signal_handler_register() and signal_handler_unregister() calls from per test files into resctrl_tests.c to properly unmount resctrl fs. In order to not add signal_handler_register()/unregister() n times, create helpers test_prepare() and test_cleanup(). Do not call ksft_exit_fail_msg() in test_prepare() but only in the per test function to keep the control flow cleaner without adding calls to exit() deep into the call chain. Adjust child process kill() call in ctrlc_handler() to only be invoked if the child was already forked.

[PATCH stable-6.6 0/2] ASoC: codecs: wsa883x: fix pops and clicks

by Johan Hovold

This is a backport of commits 0220575e65a ("ASoC: soc-dai: add flag to mute and unmute stream during trigger") 805ce81826c8 ("ASoC: codecs: wsa883x: make use of new mute_unmute_on_trigger flag") which specifically fix a loud crackling noise when starting a stream on the Lenovo ThinkPad X13s. These backports should apply to any stable tree which already has commit 3efcb471f871 ("ASoC: soc-pcm.c: Make sure DAI parameters cleared if the DAI becomes inactive") backported (e.g. 6.6.2 and 6.5.12). Note that the interaction of these commits resulted in a bad merge in mainline which is fixed up here: https://lore.kernel.org/lkml/20231123091815.21933-1-johan+linaro@kernel.org/ Johan Srinivas Kandagatla (2): ASoC: soc-dai: add flag to mute and unmute stream during trigger ASoC: codecs: wsa883x: make use of new mute_unmute_on_trigger flag include/sound/soc-dai.h | 1 + sound/soc/codecs/wsa883x.c | 7 +------ sound/soc/soc-dai.c | 7 +++++++ sound/soc/soc-pcm.c | 12 ++++++++---- 4 files changed, 17 insertions(+), 10 deletions(-) -- 2.41.0

These fixes are now in 6.7-rc1 as f0220575e65a ("ASoC: soc-dai: add flag to mute and unmute stream during trigger") 805ce81826c8 ("ASoC: codecs: wsa883x: make use of new mute_unmute_on_trigger flag") As these fix a loud scary crackling noise on the Lenovo ThinkPad X13s, is it possible to get these backported at least to stable 6.6 and 6.5?
