Hello Guoxiong Yan,

The patch a84fcdaa9058: "[media] rc: Introduce hix5hd2 IR transmitter
driver" from Aug 30, 2014, leads to the following static checker
warning:

	drivers/media/rc/ir-hix5hd2.c:111 hix5hd2_ir_config()
	warn: odd binop '0x3e80 & 0xffff0000'

drivers/media/rc/ir-hix5hd2.c
   109          /* Now only support raw mode, with symbol start from low to high */
   110          rate = DIV_ROUND_CLOSEST(priv->rate, 1000000);
   111          val = IR_CFG_SYMBOL_MAXWIDTH & IR_CFG_WIDTH_MASK << IR_CFG_WIDTH_SHIFT;
                      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
   112          val |= IR_CFG_SYMBOL_FMT & IR_CFG_FORMAT_MASK << IR_CFG_FORMAT_SHIFT;
                       ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

These seem like precedence bugs.  My guess is that the intent was:

		val =  (IR_CFG_SYMBOL_MAXWIDTH & IR_CFG_WIDTH_MASK) << IR_CFG_WIDTH_SHIFT;
		val |= (IR_CFG_SYMBOL_FMT & IR_CFG_FORMAT_MASK) << IR_CFG_FORMAT_SHIFT;

etc for the rest as well.

   113          val |= (IR_CFG_INT_THRESHOLD - 1) & IR_CFG_INT_LEVEL_MASK
   114                 << IR_CFG_INT_LEVEL_SHIFT;
   115          val |= IR_CFG_MODE_RAW;
   116          val |= (rate - 1) & IR_CFG_FREQ_MASK << IR_CFG_FREQ_SHIFT;
   117          writel_relaxed(val, priv->base + IR_CONFIG);
