From 3957ccb56e17ca839265ccb292c4c6850dcf5d32 Mon Sep 17 00:00:00 2001 From: Ivo van Doorn Date: Mon, 12 Nov 2007 15:02:40 +0100 Subject: [PATCH] rt2x00: Move duplicate code into rt2x00pci_txdone() rt2400pci, rt2500pci and rt61 require different txdone handling, but the code that pushes the frame upstream and cleans up the entry is identical to all of them. This will create the function rt2x00pci_txdone() to remove the duplicate code. Signed-off-by: Ivo van Doorn Signed-off-by: John W.
