[PATCH 1/3] devres: Clarify documentation for devres_destroy()

From: Mark Brown
Date: Thu May 03 2012 - 13:15:42 EST


It's not massively obvious (at least to me) that removing and freeing a
resource does not involve calling the release function for the resource
but rather only removes the management of it. Make the documentation more
explicit.
