4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bastien Curutchet bastien.curutchet@bootlin.com
commit a83b22754e351f13fb46596c85f667dc33da71ec upstream.
The flag attribute of the struct clk_init_data isn't initialized before the devm_clk_hw_register() call. This can lead to unexpected behavior during registration.
Initialize the entire clk_init_data to zero at declaration.
