The patch titled
Subject: rtc: recycle id when unloading a rtc driver
has been removed from the -mm tree. Its filename was
rtc-recycle-id-when-unloading-a-rtc-driver.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Vincent Palatin <vpalatin@xxxxxxxxxxxx>
Subject: rtc: recycle id when unloading a rtc driver
When calling rtc_device_unregister, we are not freeing the id used by the
driver. So when doing a unload/load cycle for a RTC driver (e.g. rmmod
rtc_cmos && modprobe rtc_cmos), its id is incremented by one. As a
consequence, we no longer have neither an rtc0 driver nor a
/proc/driver/rtc (as it only exists for the first driver).
