Subject: [PATCH 4.14 020/176] cpufreq: brcmstb-avs-cpufreq: Fix resource leaks in ->remove()

From: Christophe JAILLET <christophe.jaillet@...adoo.fr>

[ Upstream commit 3657f729b6fb5f2c0bf693742de2dcd49c572aa1 ]

If 'cpufreq_unregister_driver()' fails, just WARN and continue, so that
other resources are freed.

Fixes: de322e085995 ("cpufreq: brcmstb-avs-cpufreq: AVS CPUfreq driver for Broadcom STB SoCs")
