Subject: [PATCH] modpost: Fix ressource leak in read_dump()

Function read_dump() memory maps the input via grab_file(), but fails to call
the corresponding unmap function. Add the missing call to release_file().
Detected by Coverity: CID 1192419

Signed-off-by: Christian Engelmayer <>
Compile tested - Applies against v3.14 as well as linux-next.
