Subject: [PATCH] kernel: power: swap: mark a function as __init to save some memory
Date: Sun, 31 May 2020 23:00:59 +0200 [thread overview]
Message-ID: <20200531210059.647066-1-christophe.jaillet@wanadoo.fr> (raw)
'swsusp_header_init()' is only called via 'core_initcall'.
It can be marked as __init to save a few bytes of memory.
