From Jan Kara's cover letter:
I'm sending the seventh version of my patch series to abstract vma handling
from the various media drivers. Since the previous version there are just
minor cleanups and fixes (see detailed changelog at the end of the email).
After this patch set drivers have to know
I've cleaned up some old patch series of mine that convert the usbvision, zoran

By default, serialise open and release internal ops using a mutex.
The underlying problem is that a large proportion of the drivers do use
v4l2_fh_is_singular() in their open() handlers (struct
v4l2_subdev_internal_ops).

This patch series makes a number of API improvements to simplify checking
if an open or close of a filehandle was the first or last.

This function really returns a bool, so use that as the return type

When the filehandle is closed always return 0 and ignore the return
code from _vb2_fop_release().
Currently _vb2_fop_release() always returns 0, but this will change in
the next patch where _vb2_fop_release() will return a boolean telling the
caller if
