From 49c8b24d00b6cb06a9c3fb959a957319cc770d71 Mon Sep 17 00:00:00 2001 From: Yasuaki Ishimatsu Date: Wed, 6 Aug 2014 16:07:00 -0700 Subject: [PATCH] drivers/firmware/memmap.c: pass the correct argument to firmware_map_find_entry_bootmem() 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().
