Subject: [PATCH v2 3/3] hwmon: pwm-fan: remove no longer needed suspend/resume code
Date: Mon, 24 Apr 2017 12:01:09 +0200	[thread overview]
Message-ID: <1493028069-32003-4-git-send-email-b.zolnierkie@samsung.com> (raw)
In-Reply-To: <1493028069-32003-1-git-send-email-b.zolnierkie@samsung.com>

The suspend/resume is now properly handled by pwm-samsung driver
(pwm-fan is currently only used by ARM Exynos boards) and the old
code only handles ctx->pwm_value != 0 case. Just remove it.
