The patch titled
rtc: class driver for ppc_md RTC functions
has been removed from the -mm tree. Its filename was
rtc-class-driver-for-ppc_md-rtc-functions.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: class driver for ppc_md RTC functions
From: David Woodhouse <dwmw2@xxxxxxxxxxxxx>
This hooks up the platform-specific [gs]et_rtc_time functions so that
kernels using CONFIG_RTC_CLASS have RTC support on most PowerPC platforms.
A new driver, and one which we've been shipping in Fedora for a while
already, since otherwise RTC support breaks.
