Subject: [PATCH 4.19 043/639] mei: replace POLL* with EPOLL* for write queues.

From: Tomas Winkler <tomas.winkler@...el.com>

[ Upstream commit 03b2cbb6ea3c73e08fcf72d9ef8e286c4dcbd1fe ]

Looks like during merging the bulk POLL* -> EPOLL* replacement
missed the patch
'commit af336cabe083 ("mei: limit the number of queued writes")'

Fix sparse warning:
drivers/misc/mei/main.c:602:13: warning: restricted __poll_t degrades to integer
drivers/misc/mei/main.c:605:30: warning: invalid assignment: |=
drivers/misc/mei/main.c:605:30:    left side has type restricted __poll_t
drivers/misc/mei/main.c:605:30:    right side has type int

Fixes: af336cabe083 ("mei: limit the number of queued writes")
