resource/docs: Fix new kernel-doc warnings
The first group of warnings is caused by a "/**" kernel-doc notation marker but the function comments are not in kernel-doc format. Also add another error return value here. ../kernel/resource.c:337: warning: Function parameter or member 'start' not described in 'find_next_iomem_res' ../kernel/resource.c:337: warning: Function parameter or member 'end' not described in 'find_next_iomem_res' ../kernel/resource.c:337: warning: Function parameter or member 'flags' not described in 'find_next_iomem_res' ../kernel/resource.c:337: warning: Function parameter or member 'desc' not described in 'find_next_iomem_res' ../kernel/resource.c:337: warning: Function parameter or member 'first_lvl' not described in 'find_next_iomem_res' ../kernel/resource.c:337: warning: Function parameter or member 'res' not described in 'find_next_iomem_res' Add the missing function parameter documentation for the other warnings: ../kernel/resource.c:409: warning: Function parameter or member 'arg' not described in 'walk_iomem_res_desc' ../kernel/resource.c:409: warning: Function parameter or member 'func' not described in 'walk_iomem_res_desc' Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Borislav Petkov <bp@suse.de> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Thomas Gleixner <tglx@linutronix.de> Fixes: b69c2e20f6e4 ("resource: Clean it up a bit") Link: http://lkml.kernel.org/r/dda2e4d8-bedd-3167-20fe-8c7d2d35b354@infradead.org Signed-off-by: Ingo Molnar <mingo@kernel.org>
