[PATCH] thermal: sun8i_thermal: remove unneeded call to platform_set_drvdata()

Posted by Andrei Coardos 2 years, 4 months ago

This function call was found to be unnecessary as there is no equivalent
platform_get_drvdata() call to access the private data of the driver. Also,
the private data is defined in this driver, so there is no risk of it being
accessed outside of this driver file.

Applied, thanks

Are you checking neither dev_get_drvdata is used ?
