staging: most: block module removal while having active configfs items

2019-11-11T15:41:00+00:00

This patch avoids that core component modules are being unloaded
while the related configfs interface has active items in its directories.
It is needed to prevent the situation where the core module cannot
be unloaded anymore, because the reference count 'used by' indicates that
the module is still being used and the usage count cannot be decreased by
calling rmdir, as the configfs directory has already been removed.

to private subsystem data.

staging: most: remove string termination dependency from user space data

2019-11-07T15:26:30+00:00

This patch removes the constraint that user space data has to be terminated
with a new line character. It is needed to let the user choose how the data
is formatted.

 and Bruce W Allan.
