iio: light: gp2ap002: Fix unbalanced runtime PM on repeated event writes<\/p>\n
The IIO core does not filter duplicate writes to the event enable
\nattribute, so writing the same value twice invokes
\nwrite_event_config() twice. Enabling twice leaks a runtime PM
\nreference, preventing the device from ever suspending again;
\ndisabling twice underflows the usage count and triggers a
\n“Runtime PM usage count underflow” warning.<\/p>\n
Bail out early when the requested state matches the current state.
\nWhile at it, switch to pm_runtime_resume_and_get() so a failed
\nresume is propagated to userspace instead of silently marking the
\nevent enabled.<\/p>\n","protected":false},"excerpt":{"rendered":"
