Subject: [PATCH 13/61] Driver core: fix devres_release_all() return value

From: Adrian Bunk <bunk@...sta.de>

Every file should include the headers containing the prototypes for
it's global functions.

Since the GNU C compiler is now able to detect that the function
prototype of devres_release_all() in the header and the actual function
disagree regarding the return value, this patch also fixes this bug.
