Subject: PM: hibernate: Add __init annotation to swsusp_header_init()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=afd8d7c7f93681370f6fc2ec62f2705710eee62d;p=linux.git

PM: hibernate: Add __init annotation to swsusp_header_init()

'swsusp_header_init()' is only called via 'core_initcall'.
It can be marked as __init to save a few bytes of memory.
