[PATCH v2 1/8] platform/x86: fujitsu-laptop: distinguish current uses of device-specific data

Show all headers | View raw

In portions of the driver which use device-specific data, rename local
variables from fujitsu_bl and fujitsu_laptop to priv in order to clearly
distinguish these parts from code that uses module-wide data.
