| [ Upstream commit 2835f327bd1240508db2c89fe94a056faa53c49a ] |
| |
| Some buggy firmware and/or brand new batteries can support a charge that's |
| slightly over the reported design capacity. In such cases, the kernel will |
| report to userspace that the charging state of the battery is "Unknown", |
| when in reality the battery charge is "Full", at least from the design |
| capacity point of view. Make the fallback condition accepts capacities |
| over the designed capacity so userspace knows that is full. |
