Once I've run some tests on this branch the patches there will be added to the platform-drivers-x86/for-next branch and eventually will be included in the pdx86 pull-request to Linus for the next merge-window.

We currently have a struct ssam_request_sync and a function ssam_request_sync(). While this is valid C, there are some downsides to it. One of these is that current Sphinx versions (>= 3.0) cannot disambiguate between the two (see disucssion and pull request linked below). It instead emits a "WARNING: Duplicate C declaration" and links for the struct and function in the resulting documentation link to the same entry (i.e. both to either function or struct documentation) instead of their respective own entries. While we could just ignore that and wait for a fix, there's also a point to be made that the current naming can be somewhat confusing when searching (e.g. via grep) or trying to understand the levels of abstraction at play: We currently have struct ssam_request_sync and associated functions ssam_request_sync_[alloc|free|init|wait|...]() operating on this struct. However, function ssam_request_sync() is one abstraction level above this. Similarly, ssam_request_sync_with_buffer() is not a function operating on struct ssam_request_sync, but rather a sibling to ssam_request_sync(), both using the struct under the hood. Therefore, rename the top level request functions: ssam_request_sync() -> ssam_request_do_sync() ssam_request_sync_with_buffer() -> ssam_request_do_sync_with_buffer() ssam_request_sync_onstack() -> ssam_request_do_sync_onstack() Link: https://lore.kernel.org/all/085e0ada65c11da9303d07e70c510dc45f21315b.1656756450.git.mchehab@kernel.org/ Link: https://github.com/sphinx-doc/sphinx/pull/8313 Signed-off-by: Maximilian Luz <luzmaximilian@gmail.com> --- .../driver-api/surface_aggregator/client.rst | 8 +-- drivers/hid/surface-hid/surface_hid.c | 6 +- drivers/hid/surface-hid/surface_kbd.c | 6 +- drivers/platform/surface/aggregator/bus.c | 6 +- .../platform/surface/aggregator/controller.c | 32 +++++------ .../platform/surface/surface_acpi_notify.c | 2 +- .../surface/surface_aggregator_cdev.c | 6 +- .../surface/surface_aggregator_tabletsw.c | 2 +- include/linux/surface_aggregator/controller.h | 56 +++++++++---------- include/linux/surface_aggregator/device.h | 8 +-- 10 files changed, 66 insertions(+), 66 deletions(-)
