[PATCH 10/18] rtc: pl030: drop needless struct pl030_rtc::rtc member
From: André Draszik <andre.draszik@linaro.org>

Subsystem:
real time clock (rtc) subsystem, the rest · Maintainers:
Alexandre Belloni, Linus Torvalds
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.
