[PATCH 3.16 018/132] rtc: don't reference bogus function pointer in kdoc

[Ben Hutchings]

3.16.74-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Wolfram Sang <wsa+renesas@xxxxxxxxxxxxxxxxxxxx>

commit c48cadf5bf4becefcd0751b97995d2350aa9bb57 upstream.

The mentioned function pointer is long gone since early 2011. Remove the
reference in the comment and reword it slightly.

Fixes: 51ba60c5bb3b ("RTC: Cleanup rtc_class_ops->update_irq_enable()")
