Subject: mm: add lock release annotation on do_wp_page()
From: Namhyung Kim <namhyung@xxxxxxxxx>
The do_wp_page() releases @ptl but was missing proper annotation. Add it.
This removes following warnings from sparse:
mm/memory.c:2337:9: warning: context imbalance in 'do_wp_page' - unexpected unlock
mm/memory.c:3142:19: warning: context imbalance in 'handle_mm_fault' - different lock contexts for basic block
