regulator: core: Only increment use_count when enable_count changes ...
[ Upstream commit 7993d3a9c34f609c02171e115fd12c10e2105ff4 ]
The use_count of a regulator should only be incremented when the
enable_count changes from 0 to 1. Similarly, the use_count should
only be decremented when the enable_count changes from 1 to 0.
In the previous implementation, use_count was sometimes decremented
to 0 when some consumer called unbalanced disable,
leading to unexpected disable even the regulator is enabled by
other consumers. With this change, the use_count accurately reflects
the number of users which the regulator is enabled.
This should make things more robust in the case where a consumer does
leak references.
