Soon, this machine driver will be updated to handle a number of Tegra boards using the WM8903 codec. Rename the file in advance to reflect this.
Fix the content of tegra_wm8903.c to match the rename; replace references to Harmony board with something more generic.
* s/struct tegra_harmony/struct tegra_wm8903/ * s/harmony/machine/ # variable name * Similar rename for some functions * Similar comment fix * Similar MODULE_DESCRIPTION fix
Signed-off-by: Stephen Warren swarren@nvidia.com --- This patch is for 2.6.40, and for the ASoC subsystem
