If anyone has any objections, please let me know. ------------------ From: Alexander Sverdlin commit 5d302ed3cc80564fb835bed5fdba1e1250ecc9e5 upstream. According to "EP93xx User’s Guide", I2STXLinCtrlData and I2SRXLinCtrlData registers actually have different format. The only currently used bit (Left_Right_Justify) has different position. Fix this and simplify the whole setup taking into account the fact that both registers have zero default value. The practical effect of the above is repaired SND_SOC_DAIFMT_RIGHT_J support (currently unused).
