Hi Michael.

Please try to improve the code for human readers and/or
reduce overall object size over merely shutting up checkpatch
style warnings.

For instance:

You could reduce object size a little by eliminating the
multiple use of 0x7f and index and dereferencing the
pointer instead.

$ size drivers/staging/rtl8723bs/core/rtw_ieee80211.o*
   text	   data	    bss	    dec	    hex	filename
  10085	     76	      0	  10161	   27b1	drivers/staging/rtl8723bs/core/rtw_ieee80211.o.new
  10149	     76	      0	  10225	   27f1	drivers/staging/rtl8723bs/core/rtw_ieee80211.o.old

Something like:

uint rtw_is_cckrates_included(u8 *rate)
{
	while (*rate) {
		u8 r = *rate & 0x7f;

		if (r == 2 || r == 4 || r == 11 || r == 22)
			return true;
		rate++;
	}

	return false;
}

uint rtw_is_cckratesonly_included(u8 *rate)
{
	while (*rate) {
		u8 r = *rate & 0x7f;

		if (r != 2 && r != 4 && r != 11 && r != 22)
			return false;
		rate++;
	}

	return true;
}
