[PATCH 02/20] headers: include linux/module.h from backport.h

From: Yi Cong <[email protected]>

In v6.2, include/linux/device/driver.h includes linux/module.h, so
files using module_param() get it transitively.  In v5.4 there is no
separate device/driver.h and the include chain does not reach
module.h, causing implicit-declaration errors for module_param() and
related macros.

Include <linux/module.h> from backport.h, which is force-included
via -include on every compilation unit, ensuring module_param and
friends are always available.
