Souptick Joarder 4f86b0d956 misc: mic: scif: Fix error handling path ... [ Upstream commit a81072a9c0 ] Inside __scif_pin_pages(), when map_flags != SCIF_MAP_KERNEL it will call pin_user_pages_fast() to map nr_pages. However, pin_user_pages_fast() might fail with a return value -ERRNO. The return value is stored in pinned_pages->nr_pages. which in turn is passed to unpin_user_pages(), which expects pinned_pages->nr_pages >=0, else disaster. Fix this by assigning pinned_pages->nr_pages to 0 if pin_user_pages_fast() returns -ERRNO.
