From: Gertjan van Wingerde Date: Wed, 30 Dec 2009 10:36:32 +0000 (+0100) Subject: rt2x00: Unify rt2800 WPDMA ready waiting functions. X-Git-Tag: v2.6.34-rc1~233^2~556^2~119 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=67a4c1e24d58e0d88ed88539641631f6fc8a0cfd;p=karo-tx-linux.git rt2x00: Unify rt2800 WPDMA ready waiting functions. The rt2800pci_wait_wpdma_ready and rt2800usb_wait_wpdma_ready functions are exactly the same, so unify them into rt200lib.
