Subject: [PATCH] char: misc: assign file->private_data in all cases

In fa1f68db6ca ("drivers: misc: pass miscdevice pointer via file
private data"), the misc driver infrastructure was changed to assigned
file->private_data as a pointer to the 'struct miscdevice' that
corresponds to the device being opened.

However, this assignment was only done when the misc driver was
declaring a driver-specific ->open() operation in its
file_operations. This doesn't make sense, as the driver may not
necessarily have a custom ->open() operation, and might still be
interested in having file->private_data properly set for use in its
->read() and write() operations.

Therefore, we move the assignment of file->private_data outside of the
condition that tests whether a driver-specific ->open() operation was
defined.
