Subject: [2.6 patch] fix devres_release_all() return value

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.
