Hi, This series introduces auxiliary functions for the PCI configuration space and simplifies the read and write operations of the AER driver, reducing a lot of repetitive code.
Patch 1 adds pci_clear_config_dword() and pci_set_config_dword() helpers to reduce repetitive read-modify-write sequences when modifying PCI config space. These helpers improve code readability and maintainability. Patch 2 refactors the PCIe AER driver to use these new helpers, eliminating manual read-modify-write patterns and intermediate variable in several functions. This results in cleaner and more concise code. Changes for v5: - Rebase onto v7.4-rc2. Changes for v4: - Introduce pci_clear/set_config_dword() (Lukas) Changes for v3: - Rebase to v6.17-rc1. - Modify the patch commit messages. - Add Acked-by: Manivannan Sadhasivam <[email protected]> Changes for v2: - Modify the patch commit messages. - Add new optimizations for the functions disable_ecrc_checking, aer_enable_irq, and aer_disable_irq. v4 patch: https://patchwork.kernel.org/project/linux-pci/patch/[email protected]/ v3 series: https://patchwork.kernel.org/project/linux-pci/patch/[email protected]/ Hans Zhang (2): PCI: Introduce pci_clear/set_config_dword() PCI/AER: Use pci_clear/set_config_dword to simplify code drivers/pci/pcie/aer.c | 29 ++++++++++------------------- include/linux/pci.h | 12 ++++++++++++ 2 files changed, 22 insertions(+), 19 deletions(-) base-commit: 79eb6679ef6a0d5ea68da53a8321fb1dc72299b9 -- 2.43.0
