backlight: ipaq_micro: Make structure micro_bl_props constant 2019-10-02T13:19:00+00:00 Nishka Dasgupta nishkadg.linux@gmail.com 2019-08-13T08:58:55+00:00 7050a7c3747787c3f9ba94df59eb7e9e018bbdf2 Static structure micro_bl_props, having type backlight_properties, is used only once, when it is passed as the last argument to function devm_backlight_device_register(). devm_backlight_device_register() is defined with its last parameter being declared constant. Hence make micro_bl_props itself constant as well. Issue found with Coccinelle.
