The patch titled
mxser: spin_lock() => spin_lock_irq()
has been removed from the -mm tree. Its filename was
mxser-spin_lock-=-spin_lock_irq.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: mxser: spin_lock() => spin_lock_irq()
From: Dan Carpenter <error27@xxxxxxxxx>
This should be spin_lock_irq() to match the spin_unlock_irq(). Originally
it was a lock_kernel() but we switched everything to spin_lock_irq() last
November.
[akpm@xxxxxxxxxxxxxxxxxxxx: fix the MOXA_ASPP_MON case too (per Jiri)]
