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;
}
