Subject: [PATCH] gpio-charger: use cansleep version of gpio_set_value
Date: Tue, 22 May 2012 14:20:04 +0530 [thread overview]
Message-ID: <1337676604-22836-1-git-send-email-praithatha@nvidia.com> (raw)
Context of gpio_charger_get_property is sleepable so we should
use gpio_set_value_cansleep instead of gpio_set_value.
It will remove WARN_ON incase of using gpio from i2c-to-gpio
expander like pca953x.
