The patch titled
rtc: convert LEAP_YEAR into an inline
has been removed from the -mm tree. Its filename was
rtc-convert-leap_year-into-an-inline.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: rtc: convert LEAP_YEAR into an inline
From: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx>
- the LEAP_YEAR macro is buggy - it references its arg multiple times.
Fix this by turning it into a C function.
- give it a more approriate name
- Move it to rtc.h so that other .c files can use it, instead of copying it.
