Fsync is really an inode operation (AFAICS) so a doing it on a O_RDONLY
file descriptor should flush any data written through an O_WRONLY file
descriptor for example.
To make this work correctly in case the file is copied up after being
opened for read, intercept the fsync operation, similarly to

being opened read-only and mapped shared.

Introduce IIO trigger specifiers, so there are:
- IIO trigger providers, e.g. dt nodes designated with
#io-trigger-cells=
- IIO trigger consumers, e.g. phandles listed in io-triggers = <...>.
Those can be identified by names by us

Lost of calls to of_platform_populate() are not unbalanced by a call
to of_platform_depopulate(). This create issues while drivers are
bind/unbind.
In way to solve those issues is to add devm_of_platform_populate()
which will call of_platform_depopulate() when the device is unbound
from the bus.

A cleanup patch left one local variable without a reference:

This removes the declaration too.
