[PATCH 00/30] Last batch of patches to clean up Misc

[PATCH 00/30] Last batch of patches to clean up Misc

[Lee Jones]

This set is part of a larger effort attempting to clean-up W=1
kernel builds, which are currently overwhelmingly riddled with
niggly little warnings.

After these patches are applied, the build system no longer
complains about any W=0 nor W=1 level warnings in drivers/misc.

Hurrah!

[PATCH 01/30] misc: genwqe: card_ddcb: Fix a variety of kerneldoc issues

[Lee Jones]

Including; demoting file header from kerneldoc to standard comment/
header, adding a variety of missing function argument documentation,
re-ordering of #defines i.e. not placed between kerneldoc headers
and the functions they are documenting and re-documenting of changed/
renamed arguments.

Fixes the following W=1 kernel build warnings:

[PATCH 02/30] misc: genwqe: card_sysfs: Demote function/file headers from kerneldoc

[Lee Jones]

There has been no attempt to provide documentation for these function's
arguments, so align with the remainder of the file and just treat
them as standards function headers.

[PATCH 03/30] misc: genwqe: card_debugfs: Demote file header from kerneldoc

Kerneldoc does not understand file headers.  There is therefor
no reason for them to use the syntax.

[PATCH 08/30] misc: ibmasm: r_heartbeat: Demote function headers from kerneldoc

[PATCH 09/30] misc: mic: host: mic_x100: Move declaration of mic_x100_intr_init[] into c-file

[Lee Jones]

mic_x100_intr_init[] is only ever used in mic_x100.c, so instead
of listing to the compiler complain about unused static arrays
simply move it into the c-file for direct consumption.  This way
it can stay 'static'.

[PATCH 19/30] misc: mic: scif: scif_api: Demote scif_accept() function header

[Lee Jones]

The correct format is not used and no attempt has been made
to document the function arguments.  Makes sense to just demote
the header back down to a simple comment.

Fixes the following W=1 warnings:

 drivers/misc/mic/scif/scif_api.c:739: warning: Function parameter or member 'epd' not described in 'scif_accept'
 drivers/misc/mic/scif/scif_api.c:739: warning: Function parameter or member 'peer' not described in 'scif_accept'

[PATCH 20/30] misc: mic: scif: scif_epd: Describe missing 'scifdev' argument(s)

For some reason (copy 'n' paste error?) the passed in pointers to
'struct scif_dev scifdev' weren't described throughout the source

[PATCH 25/30] misc: mic: scif: scif_rma: Repair a bunch of kerneldoc issues

[Lee Jones]

Firstly, for some reason documentation of all 'scifdev' arguments
are missing, so apply those.  Also remove 2 descriptions of 'ep'
which appear to document non-existent function arguments.

[PATCH 27/30] misc: cxl: hcalls: Demote half-assed kerneldoc attempt

[PATCH 28/30] misc: ocxl: config: Provide correct formatting to function headers

[Lee Jones]

A nice attempt was made to provide kerneldoc headers for
read_template_version() and read_afu_lpc_memory_info() however,
the provided formatting does not match what is expected by
kerneldoc.

Fixes the following W=1 warnings:

[PATCH 30/30] misc: cxl: flash: Remove unused pointer

[Lee Jones]

The DRC index pointer us updated on an OPCODE_ADD, but never
actually read.  Remove the used pointer and shift up OPCODE_ADD
to group with OPCODE_DELETE which also provides a noop.

Fixes the following W=1 kernel build warning:
