2020-10-15docs: scsi: target.rst: remove iSCSI transport class kernel-doc markupMauro Carvalho Chehab1-12/+0
This is already included at scsi.rst. So, remove the duplication, in order to avoid Sphinx warnings. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-10-15docs: basics.rst: move kernel-doc workqueue markups to workqueue.rstMauro Carvalho Chehab1-9/+0
As there's already a rst file with workqueue markups, containing part of them, move the other definitions, in order to avoid warnings with Sphinx. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-10-15docs: remove sound API duplicationMauro Carvalho Chehab2-55/+0
The sound API is documented on two different parts: under Documentation/driver-api/sound.rst and under Documentation/sound/kernel-api/alsa-driver-api.rst. The alsa-driver-api.rst seems more complete, and APIs are split per type. There's just one missing kernel-doc markup there. Add it and drop the duplicated one.

2020-10-15docs: get rid of :c:type explicit declarations for structsMauro Carvalho Chehab20-58/+58
The :c:type:`foo` only works properly with structs before Sphinx 3.x. On Sphinx 3.x, structs should now be declared using the .. c:struct, and referenced via :c:struct tag. As we now have the automarkup.py macro, that automatically convert: struct foo into cross-references, let's get rid of that, solving several warnings when building docs with Sphinx 3.x.

2020-10-15docs: remove some replace macros like |struct foo|Mauro Carvalho Chehab2-42/+33
There are three files with replace macros for structs, mapping them into Sphinx 2.x C domain references. Well, this is broken on Sphinx 3.x. Also, for Sphinx 2.x, the automarkup macro should be able to take care of them. So, let's just drop those. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

2020-10-08docs: net: 80211: reduce docs build timeMauro Carvalho Chehab3-492/+199
the files under /80211 calls kernel-doc script 207 times, one for each single function and doc chapter. Due to that, it takes a lot of time handling it: $ touch Documentation/driver-api/80211/*rst && time make SPHINXDIRS=driver-api/80211 htmldocs ... real 0m22,928s user 0m21,644s sys 0m1,334s Reduce the build time by doing only one kernel-doc call per functions that belong to the same group. With that, there's now 50 calls to kernel-doc, which makes the build time for those docs 62% faster: $ touch Documentation/driver-api/80211/*rst && time make SPHINXDIRS=driver-api/80211 htmldocs ... real 0m8,666s user 0m8,084s sys 0m0,642s As a side effect, it should now be easier to add newer functions, as there's no need to repeat the kernel-doc pattern.

So, declarations like this are not valid: .. c:function:: int (*adap_enable)(struct cec_adapter *adap, bool enable); Also, no blank lines are allowed after ".. c:function:", and continuation lines should be like: .. c:function: int (void foo, \ int bar); Change the logic there, in order to avoid lots of warnings when built with Sphinx 3.x.

Following functions are only used internally, not by drivers: - devm_drm_dev_init Also, now that we have a very slick and polished way to allocate a drm_device with devm_drm_dev_alloc, update all the docs to reflect the new reality. Mostly this consists of deleting old and misleading hints. Two main ones: - it is no longer required that the drm_device base class is first in the structure. devm_drm_dev_alloc can cope with it being anywhere - obviously embedded now strongly recommends using devm_drm_dev_alloc v2: Fix typos (Noralf) v3: Split out the removal of drm_dev_init, that's blocked on some discussions on how to convert vgem/vkms/i915-selftests.
