Dear Maintainer,

I recently upgraded the Linux kernel to 3.16. Previously, the WiFi on my laptop required me to compile a driver acquired from https://github.com/lwfinger/rtl8723au 

Since kernel version 3.15, this driver is now included. After installing the newest kernel for Debian, I get the following output in /var/log/kern.log:

Sep 30 11:31:09 hostname kernel: [  324.839269] rtl8723au: Loading firmware rtlwifi/rtl8723aufw_B.bin
Sep 30 11:31:09 hostname kernel: [  324.839296] rtl8723au 1-1.4:1.2: firmware: failed to load rtlwifi/rtl8723aufw_B.bin (-2)
Sep 30 11:31:09 hostname kernel: [  324.839301] rtl8723au 1-1.4:1.2: Direct firmware load failed with error -2
Sep 30 11:31:09 hostname kernel: [  324.839305] rtl8723au 1-1.4:1.2: Falling back to user helper
Sep 30 11:31:09 hostname kernel: [  324.839730] rtl8723au: request_firmware load failed

The hardware I'm running is a Lenovo Ideapad Yoga 13.
