Subject: [PATCH v2 06/11] power: bq25890: update state on property read
Date: Sun, 03 May 2020 17:21:12 +0200 [thread overview]
Message-ID: <5c8e8f4c5a7fc2cecb62342f9a964f69f3fde7ae.1588517058.git.mirq-linux@rere.qmqm.pl> (raw)
In-Reply-To: <cover.1588517058.git.mirq-linux@rere.qmqm.pl>
Edge interrupts from the charger may be lost or stuck in fault mode
since probe(). Check if something changed everytime userspace wants
some data.
