Subsystem:
broadcom stb avs cpufreq driver, cpu frequency scaling framework, the rest · Maintainers:

From: Florian Fainelli <f.fainelli@gmail.com>
[ Upstream commit 22a26cc6a51ef73dcfeb64c50513903f6b2d53d8 ]
There is a logical error in brcm_avs_is_firmware_loaded() whereby if the
firmware returns -EINVAL, we will be reporting this as an error. The
comment is correct, the code was not.
