Subject: [PATCH 5.4 071/102] staging: greybus: loopback_test: fix poll-mask build breakage

From: Johan Hovold <johan@...nel.org>

commit 8f3675be4bda33adbdc1dd2ab3b6c76a7599a79e upstream.

A scripted conversion from userland POLL* to kernel EPOLL* constants
mistakingly replaced the poll flags in the loopback_test tool, which
therefore no longer builds.

Fixes: a9a08845e9ac ("vfs: do bulk POLL* -> EPOLL* replacement")
Cc: stable <stable@...r.kernel.org>     # 4.16
