Rui Miguel Silva b5fbe819af greybus: power_supply: invalidate cache at update request When we receive a update request we shall not trust the cache mechanism and for that we need a way to invalidate the cache. Add a field that will control the cache status and refactor the code to check if cache is valid in a helper function. This will fix the scenario where an update request is received within the cache expiration time after a previous update as happened and would be ignored.

Rui Miguel Silva b5fbe819af greybus: power_supply: invalidate cache at update request

When we receive a update request we shall not trust the cache mechanism
and for that we need a way to invalidate the cache. Add a field that
will control the cache status and refactor the code to check if cache is
valid in a helper function.

This will fix the scenario where an update request is received within
the cache expiration time after a previous update as happened and would
be ignored.
