From 61ed1dca1645d2dd64c83a01f728dfd59fa789b6 Mon Sep 17 00:00:00 2001 From: Nickolai Zeldovich Date: Sat, 5 Jan 2013 14:14:08 -0500 Subject: ALSA: au88x0: fix incorrect left shift vortex_wt_setdsout performs bit-negation on the bit position (wt&0x1f) rather than on the resulting bitmask. This code is never actually invoked (vortex_wt_setdsout is always called with en=1), so this does not currently cause any problem, and this patch is simply cleanup.
