[Dan Carpenter <dan.carpenter@oracle.com>]

Hello Michael Sit Wei Hong,

The patch 9c3bab3c4f15: "ASoC: Intel: KMB: Enable TDM audio capture"
from Aug 11, 2020, leads to the following static checker warning:

	sound/soc/intel/keembay/kmb_platform.c:518 kmb_dai_hw_params()
	warn: potential ! vs ~ typo

sound/soc/intel/keembay/kmb_platform.c
   502          }
   503  
   504          config->chan_nr = params_channels(hw_params);
   505  
   506          switch (config->chan_nr) {
   507          case 8:
   508          case 4:
   509                  /*
   510                   * Platform is not capable of providing clocks for
   511                   * multi channel audio

   513                  if (kmb_i2s->master)
   514                          return -EINVAL;
   515  
   516                  write_val = ((config->chan_nr / 2) << TDM_CHANNEL_CONFIG_BIT) |
   517                                  (config->data_width << DATA_WIDTH_CONFIG_BIT) |
   518                                  !MASTER_MODE | TDM_OPERATION;
                                        ^^^^^^^^^^^^
MASTER_MODE is BIT(13).  It's unclear what this is supposed to be.  My
best guess is that the ! should just be deleted.

   520                  writel(write_val, kmb_i2s->pss_base + I2S_GEN_CFG_0);

   522          case 2:

   525                   * 2 channel master mode

   527                  if (!(kmb_i2s->master))
   528                          return -EINVAL;
