[RFT/PATCH 3/7] arm: omap: smartreflex: use dev_get_drvdata()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When we need to fetch struct omap_sr on PM
handlers, there's no need to access platform_data.

Instead, we can use dev_get_drvdata(dev) like
other drivers do.
