[PATCH] drivers/base - fix sparse warnings There are a number of sparse warnings from the latest sparse snapshot being generated from the drivers/base build. The main culprits are due to the initialisation functions not being declared in a header file. Also, the firmware.c file should include <linux/device.h> to get the prototype of firmware_register() and firmware_unregister(). This patch moves the init function declerations from the init.c file to the base.h, and ensures it is included in all the relevant c sources. It also adds <linux/device.h> to the included headers for firmware.c. The patch does not solve all the sparse errors generated, but reduces the count significantly. drivers/base/core.c:161:1: warning: symbol 'devices_subsys' was not declared.
