[PATCH 0/2] ACPICA: Events: Fix GPE enabling issues related to edge-triggered GPEs
There are 2 issues related to the enabling of GPEs: 1. Currently, our code clears GPE before enabling it. In case of edge triggered GPEs, doing this risks GPE losses. 2. For edge-triggered GPEs, enabling it is not sufficiently to trigger an already triggered GPE, we need to poll the GPE once it is enabled. This patchset fixes these 2 problems.
