Subject: [PATCH 1/2] firmware/memmap: pass the correct argument to firmware_map_find_entry_bootmem()
Date: Mon, 7 Jul 2014 04:29:19 +0900 [thread overview]
Message-ID: <53B9A38F.9000609@jp.fujitsu.com> (raw)
firmware_map_add_hotplug() calls firmware_map_find_entry_bootmem() to get
free firmware_map_entry. But end arguments is not correct. So
firmware_map_find_entry_bootmem() cannot not find firmware_map_entry.
The patch passes the correct end argument to firmware_map_find_entry_bootmem().
