The patch titled
rtc: release correct region in error path
has been removed from the -mm tree. Its filename was
rtc-release-correct-region-in-error-path.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: rtc: release correct region in error path
From: Bjorn Helgaas <[EMAIL PROTECTED]>
The misc_register() error path always released an I/O port region,
even if the region was memory-mapped (only mips uses memory-mapped RTC,
as far as I can see).
