staging: ashmem: Fix ASHMEM_PURGE_ALL_CACHES return value
Hopefully this isn't too late for 3.12.
In commit 7dc19d5aff (convert shrinkers to new count/scan API)
the return value to PURGE_ALL_CACHES was dropped, causing -EPERM
to always be returned.
This patch re-adds the ret assignment, setting it to the the
ashmem_shrink_count(), which is the lru_count.
(Sorry this was missed in the review!)
Fixes: 7dc19d5affd7 ("convert shrinkers to new count/scan API")
