From fe7256971fbaeac868c35c2dbd34a7bbbdc0622b Mon Sep 17 00:00:00 2001 From: Gertjan van Wingerde Date: Tue, 29 Jun 2010 21:40:34 +0200 Subject: [PATCH] rt2x00: Move filling of TX URB to rt2x00usb_kick_tx_entry function. There is no need to fill the TX URB this early, and moving it to the rt2x00usb_kick_tx_entry function allows us to merge the PCI and USB variants of the write_tx_data function.
