*** IMPORTANT *** This is part 1 - only drivers in acpi directory to ease up review process. Rest of the drivers will be handled in separate patchsets. Currently drivers support ACPI event handlers by defining .notify callback in acpi_device_ops. This solution is suboptimal as event handler installer installs intermediary function acpi_notify_device as a handler in every driver. Also this approach requires extra variable 'flags' for specifying event types that the driver want to subscribe to. Additionally this is a pre-work required to align acpi_driver with platform_driver and eventually replace acpi_driver with platform_driver. Remove .notify callback from the acpi_device_ops. Replace it with each driver installing and removing it's event handlers. This is part 1 - only drivers in acpi directory to ease up review process. v7: - fix warning by declaring acpi_nfit_remove_notify_handler() as static v6: - fixed unnecessary RCT in all drivers, as it's not a purpose of this patch series - changed error label names to simplify them - dropped commit that remove a comma - squashed commit moving code for nfit - improved nfit driver to use devm instead of .remove() - re-based as Rafael changes [1] are merged already v5: - rebased on top of Rafael changes [1], they're not merged yet - fixed rollback in multiple drivers so they don't leak resources on failure - made this part 1, meaning only drivers in acpi directory, rest of the drivers will be handled in separate patchsets to ease up review v4: - added one commit for previously missed driver sony-laptop, refactored return statements, added NULL check for event installer v3: - lkp still reported some failures for eeepc, fujitsu and toshiba_bluetooth, fix those v2: - fix compilation errors for drivers [1]: https://lore.kernel.org/linux-acpi/1847933.atdPhlSkOF@kreacher/ Michal Wilczynski (9): acpi/bus: Introduce wrappers for ACPICA event handler install/remove acpi/bus: Set driver_data to NULL every time .add() fails acpi/ac: Move handler installing logic to driver acpi/video: Move handler installing logic to driver acpi/battery: Move handler installing logic to driver acpi/hed: Move handler installing logic to driver acpi/nfit: Move handler installing logic to driver acpi/nfit: Remove unnecessary .remove callback acpi/thermal: Move handler installing logic to driver drivers/acpi/ac.c | 29 ++++++++++++++++++------- drivers/acpi/acpi_video.c | 22 ++++++++++++++++--- drivers/acpi/battery.c | 26 +++++++++++++++++----- drivers/acpi/bus.c | 30 +++++++++++++++++++++++++- drivers/acpi/hed.c | 17 ++++++++++++--- drivers/acpi/nfit/core.c | 45 +++++++++++++++++++++++++++------------ drivers/acpi/thermal.c | 25 +++++++++++++++++----- include/acpi/acpi_bus.h | 6 ++++++ 8 files changed, 161 insertions(+), 39 deletions(-) -- 2.41.0
