Subject: [PATCH] slimbus: ngd: get drvdata from correct device
Date: Fri, 17 Apr 2020 10:36:18 +0100 [thread overview]
Message-ID: <20200417093618.7929-1-srinivas.kandagatla@linaro.org> (raw)
Get drvdata directly from parent instead of ngd dev, as ngd
dev can probe defer and previously set drvdata will become null.
