[PATCH] [media] v4l2-subdev.rst: correct information about v4l2 events

From: Michael Rodin
Date: Wed May 27 2020 - 12:22:08 EST


Remove description of non-existing v4l2_subdev.nevents and replace the
undefined flag V4L2_SUBDEV_USES_EVENTS by the correct flag
V4L2_SUBDEV_FL_HAS_EVENTS, which is already documented in v4l2_subdev.flags

Fixes: commit 02adb1cc765b ("[media] v4l: subdev: Events support")
