This bug is awaiting verification that the linux-lowlatency- hwe-6.2/6.2.0-1018.18~22.04.1 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy-linux- lowlatency-hwe-6.2' to 'verification-done-jammy-linux-lowlatency- hwe-6.2'. If the problem still exists, change the tag 'verification- needed-jammy-linux-lowlatency-hwe-6.2' to 'verification-failed-jammy- linux-lowlatency-hwe-6.2'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

The main kernel and pretty much every kernel apart from linux-kvm, has CONFIG_PWM=y. * The problem was caught when lunar:linux-kvm was cranked and build failed with the following error: ``` In file included from /build/lunar/drivers/acpi/acpi_lpss.c:23: /build/lunar/include/linux/pwm.h:486:19: error: redefinition of 'devm_pwmchip_add' 486 | static inline int devm_pwmchip_add(struct device *dev, struct pwm_chip *chip) | ^~~~~~~~~~~~~~~~ /build/lunar/include/linux/pwm.h:481:19: note: previous definition of 'devm_pwmchip_add' with type 'int(struct device *, struct pwm_chip *)' 481 | static inline int devm_pwmchip_add(struct device *dev, struct pwm_chip *chip) | ^~~~~~~~~~~~~~~~ ``` [Fix] * Revert the commit. * Because this affects only linux:kvm, it is necessary to apply this fix for lunar:linux-kvm for cycle 2023.10.02, but the main kernel can wait for the next cycle. [Test plan] * Since linux-kvm was the only kernel that had this issue, I applied the patch to kvm after I rebased the latest changes from the parent and did a build test. * I also did a build test for linux:main just to make sure [Where problems could occur] * This change is pretty non-invasive, so nowhere To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2039542/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
