Subject: [PATCH][PPC32] fix locking bugs in mv64x60 code
Date: Wed, 02 Feb 2005 17:20:03 -0700	[thread overview]
Message-ID: <42016E33.9070804@mvista.com> (raw)

[Original patch slightly edited by mgreer]

This patch fixes 2 SMP deadlocks. The first is that mv64x60_read() was 
returning before the unlock. The second was mv64x60_modify() locks the spin 
lock and calls mv64x60_read() and mv64x60_write() which also lock the same spin lock.

Please apply.
