config EXTRA_FIRMWARE not compiling muliple files

[noman pouigt]

Hello Folks,

CONFIG_FW_LOADER=y
CONFIG_FIRMWARE_IN_KERNEL=y
CONFIG_EXTRA_FIRMWARE="first_image" "second_image"

request_firmware for "first_image" is passing but for "second_image"
the loading is not happening. Is this a known scripting issue?

I get "Request firmware defered -11". Please advice.

Kernel version:
 VERSION = 4
 PATCHLEVEL = 4
 SUBLEVEL = 21
 EXTRAVERSION =

Thanks,
