firmware: failed to load rtl_bt/rtl8723b_config.bin (-2)

[mks-h]

When turning on from suspend, I always see new messages about failing to load rtl_bt/rtl8723b_config. Reading the kernel logs, I found the following segment to repeat all the time:

Notes:
The hid-generic 0005:046D:B031.000A identifier increments the last section (.000A) with each repetition.
The number in filesystems sync: 0.037 seconds always slightly differs.

This is not a Vanilla specific issue, it happens of Fedora as well.
