[PATCH] powerpc: Fix sound driver use of i2c
The PowerMac sound drivers used to rely on a "bug" of the i2c-keywest
driver that implemented I2C_SMBUS_BLOCK_DATA incorrectly, that is it did
what I2C_SMBUS_I2C_BLOCK_DATA should have done. The new i2c-powermac
driver that replaces keywest has this bug fixed, thus the sound drivers
must be fixed too.
