Yes, this new change would break devices with firmware older than ver 14.2(released on our vendor tree in March 2016). The older firmware in the linux-firmware repository is close to 2 years old and not being used with the staging driver even before this change  was submitted. Developers picked up the firmware mostly from one of our vendor trees on github.

To resolve this confusion about firmware location, I submitted a patch to linux-firmware to make the latest firmware available through this channel. Below are the details. The driver currently does not enforce usage of new firmware but would fail to properly configure the older firmware.

Subject: [PATCH] linux-firmware: wilc1000: Update firmware for wilc1000
Date: Wed, 5 Apr 2017 13:57:19 +0530


This commit updates the wilc1000 firmware
to the latest version and replaces the three older
firmware binaries as we no longer need seperate binaries
for all the wlan modes.
