      nl80211: docs: add a description for s1g_cap parameter · 8a50c057
      Mauro Carvalho Chehab authored
      Changeset df78a0c0 ("nl80211: S1G band and channel definitions")
      added a new parameter, but didn't add the corresponding kernel-doc
      markup, as repoted when doing "make htmldocs":
      
      	./include/net/cfg80211.h:471: warning: Function parameter or member 's1g_cap' not described in 'ieee80211_supported_band'

      usb: docs: document altmode register/unregister functions · 1b774391
      Mauro Carvalho Chehab authored
      The typec_bus.rst asks for documentation of those two
      functions, but they don't exist:
      
      	./drivers/usb/typec/bus.c:1: warning: 'typec_altmode_unregister_driver' not found
      	./drivers/usb/typec/bus.c:1: warning: 'typec_altmode_register_driver' not found
      
      Also, they're not declared on bus.c but, instead, at a header
      file (typec_altmode.h).
      
      So, add documentation for both functions at the header and
      change the kernel-doc markup under typec_bus.rst to point
      to the right place.
      
      While here, also place the documentation for both structs
      declared on typec_altmode.h at the rst file.

      kunit: test.h: fix a bad kernel-doc markup · 623050ae

      The right way to describe a function is:
      
      	name - description
      
      Instead, kunit_remove_resource was using:
      
      	name: description
      
      Causing it to be improperly parsed.

      kunit: test.h: solve kernel-doc warnings · 38d9b909
      Mauro Carvalho Chehab authored
      There are some warnings there:
      	./include/kunit/test.h:90: warning: Function parameter or member 'name' not described in 'kunit_resource'
      	./include/kunit/test.h:353: warning: Function parameter or member 'res' not described in 'kunit_add_resource'

      	./include/kunit/test.h:367: warning: Excess function parameter 'name_data' description in 'kunit_add_named_resource'
      
      Address them, ensuring that all non-private arguments will
      be properly described. With that regards, at struct kunit_resource,
      the free argument is described as user-provided. So, this
      doesn't seem to belong to the "private" part of the struct.

      block: bio: fix a warning at the kernel-doc markups · 5b874af6
      Mauro Carvalho Chehab authored
      Using "@bio's parent" causes the following waring:
      	./block/bio.c:10: WARNING: Inline emphasis start-string without end-string.
      
      The main problem here is that this would be converted into:
      
      	**bio**'s parent
      
      By kernel-doc, which is not a valid notation. It would be
      possible to use, instead, this kernel-doc markup:
      
      	``bio's`` parent
      
      Yet, here, is probably simpler to just use an altenative language:
      
      	the parent of @bio

      chanseset b3a7bb1851c8 ("docs: get rid of :c:type explicit declarations for structs")
      removed several :c:type: markups, except by one.
      
      Now, Sphinx 3.x complains about it:

      As, on Sphinx 3.x, the right markup is c:struct:`foo`.
      
      So, let's remove it, relying on automarkup.py to convert it.

      Sphinx C parser for the C domain is now more pedantic when
