Subject: drivers/firmware/memmap.c: pass the correct argument to firmware_map_find_entry_bootmem()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=49c8b24d;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

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().
