[patch 12/41] lib: bitmap: fix many kernel-doc warnings

[Andrew Morton <akpm@linux-foundation.org>]

From: Randy Dunlap <rdunlap@infradead.org>
Subject: lib: bitmap: fix many kernel-doc warnings

Fix kernel-doc warings in lib/bitmap.c:

../lib/bitmap.c:498: warning: Function parameter or member 'buf' not described in 'bitmap_print_to_buf'
../lib/bitmap.c:498: warning: Function parameter or member 'maskp' not described in 'bitmap_print_to_buf'
../lib/bitmap.c:498: warning: Function parameter or member 'nmaskbits' not described in 'bitmap_print_to_buf'
../lib/bitmap.c:498: warning: Function parameter or member 'off' not described in 'bitmap_print_to_buf'
../lib/bitmap.c:498: warning: Function parameter or member 'count' not described in 'bitmap_print_to_buf'
../lib/bitmap.c:561: warning: contents before sections
../lib/bitmap.c:606: warning: Function parameter or member 'buf' not described in 'bitmap_print_list_to_buf'
../lib/bitmap.c:606: warning: Function parameter or member 'maskp' not described in 'bitmap_print_list_to_buf'
../lib/bitmap.c:606: warning: Function parameter or member 'nmaskbits' not described in 'bitmap_print_list_to_buf'
../lib/bitmap.c:606: warning: Function parameter or member 'off' not described in 'bitmap_print_list_to_buf'
../lib/bitmap.c:606: warning: Function parameter or member 'count' not described in 'bitmap_print_list_to_buf'
../lib/bitmap.c:819: warning: missing initial short description on line:
 * bitmap_parselist_user()

This still leaves 15 warnings for function return values not described,
similar to this one:
bitmap.c:890: warning: No description found for return value of 'bitmap_parse'

Fixes: 1fae562983ca ("cpumask: introduce cpumap_print_list/bitmask_to_buf to support large bitmask and list")
Fixes: 4b060420a596 ("bitmap, irq: add smp_affinity_list interface to /proc/irq")
