Subject: [PATCH 07/10] Input: eeti_ts - use gpio_get_value_cansleep
Date: Tue, 28 Feb 2017 14:46:29 -0800 [thread overview]
Message-ID: <20170228224632.3401-7-dmitry.torokhov@gmail.com> (raw)
In-Reply-To: <20170228224632.3401-1-dmitry.torokhov@gmail.com>
We are reading GPIO state in a non-atomic context (workqueue), so we can
use "cansleep" variant, and thus make the driver available on systems where
GPIO controllers require sleeping when reading GPIO state.
