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;
}

Hi Joe,

I agree that it's better to improve the code than just silence
warnings.

Thanks for your advice.

The patch has been added to staging-testing already.
I will send patches with your suggestions the next days.

Thanks again.

Would it be preferred to declare the variable at the functions beginning,
or doesn't it matter regarding coding style?

uint rtw_is_cckratesonly_included(u8 *rate)
{
         u8 r;

         while (*rate) {
                 r = *rate & 0x7f;
         ...

Best,
Michael

Not really.

It's generally preferred to have declarations in the
nearest possible open brace to allow the compiler to
reduce the overall stack space consumed by the function.

For example prefer:

int some_function(int arg, void *pointer)
{
	if (arg == 1} {
		struct foo a = *(struct foo *)pointer;
		...
	} else if (arg == 2) {
		struct bar b = *(struct bar *)pointer;
		...
	}
}

over

int some_function(int arg, void *pointer)
{
	struct foo a;
	s
truct bar b;

	if (arg == 1} {
		a = *(struct foo *)pointer;
		...
	} else if (arg == 2) {
		b = *(struct bar *)pointer;
		...
	}
}

as a and b could use the same stack in the
first example but not the second.
