qcacld-2.0 to qcacld-3.0 propagation After boot when driver is loaded for the first time, driver call the regulatory_hint with default country. From kernel 3.18 onward regulatory_hint removes the REGULATORY_CUSTOM_REG flag from wiphy flags. But once reg notifier is called for the country the wiphy flags are restored from the original flags stored in driver. Now if driver is unloaded and loaded again, kernel calls the reg notifier for the last country set by driver before unload. In static drivers the global static flag init_by_driver will remain true even after unload and load and thus init_by_reg_core is not set to true when kernel calls the reg notifier. Thus driver ends up sending reg hint to kernel with same country, this reg hint removes the REGULATORY_CUSTOM_REG flag from wiphy flags and is dropped in the kernel as country has not changed. As reg notifier is not called for the reg hint and wiphy flags are not restored. To avoid changing of wiphy flags, reset the global static reg params during wiphy unregisteration.
