From: Daniel Thompson <daniel.thompson@xxxxxxxxxx>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit 58eb97c99da6a82c556ddec70683eb3863d4f617 upstream.
After 07d410e0) serial: sirf: fix spinlock deadlock issue it is no longer
possiblet to compile this driver. The rename of one of the spinlocks is
faulty. After looking at the original patch I believe this is the correct
fix.
Compile tested using ARM's multi_v7_defconfig
