Subject: [PATCH 12/13] SONIC: small fix and cleanup Cc: Thomas Bogendoerfer , Jeff Garzik , netdev@vger.kernel.org, linux-mips@linux-mips.org From: Finn Thain Fix a potential problem in the timeout handling: don't free the DMA buffers before resetting the chip. Also a trivial cleanup. Bring macsonic and jazzsonic into sync.
