| 2025-03-05 | rtc: sd2405al: drop needless struct sd2405al::rtc member | André Draszik | |
| The memory pointed to by the ::rtc member is managed via devres, and no code in this driver uses it past _probe(). We can drop it from the structure and just use a local temporary variable, reducing runtime memory consumption by a few bytes.
