For QCA6390 we first need to call free_irq() and only then disable_msi(). Otherwise a kernel BUG below will happen. Also free core, hal_srng and ce resources during ath11k_pci_remove().

With QCA6390 when doing rmmod the kernel crashed. The reason was that the destroy functions ath11k_debugfs_pdev_destroy() and ath11k_debugfs_soc_destroy() accidentally had swapped the debugfs directories and ath11k_debugfs_soc_destroy() was removing an already removed directory, which crashed the kernel. The source of confusion is badly named function and variable names. I think the best way to clean this up is actually to merge the corresponding functions, but that's for another patch. Let's first just fix the crash.

Thank you for your contribution. The WSL team has discussed and decided that the WSL 2 Linux kernel GitHub repo is not taking pull requests. The WSL 2 Linux kernel repo was always intended to provide the additional infrastructure necessary to build and release the kernel component of WSL 2. It was never designed to replace the current existing community and feedback channels for WSL, especially through https://github.com/microsoft/WSL. This is why we are not accepting issues or pull requests through this repository. We understand that this should have been better communicated and implemented from the beginning. While we understand that it is frustrating to have a PR closed, it is never our intention to ignore feedback or stifle community discussions. We are taking this opportunity to increase transparency on how we work with the WSL community and ensure all members are routed to the appropriate resources. If you would like contribute to, discuss, or report an issue relating to WSL, or the WSL 2 Linux kernel configuration, please do so at the WSL GitHub. The team is actively monitoring and responding to user feedback there: https://github.com/microsoft/WSL. The WSL 2 Linux kernel is based on the Linux version from https://www.kernel.org/. If you would like to contribute to or report an issue on the Linux kernel in general, please do so on the upstream Linux GitHub: https://www.kernel.org/doc/html/latest/process/submitting-patches.html. |

Commit a0384ec ("clk: qcom: smd-rpm: De-duplicate identical entries") introduces the following regression on MSM8936/MSM8939, as RPM_SMD_PCNOC_A_CLK gets pointed to pcnoc_clk by mistake. Fix it by correcting the clock to pcnoc_a_clk.
