Here's the original code:
int rtw_get_bit_value_from_ieee_value23a(u8 val)
{
unsigned char dot11_rate_table[]=
{2, 4, 11, 22, 12, 18, 24, 36, 48, 72, 96, 108, 0};
int i = 0;
while (dot11_rate_table[i] != 0) {
if (dot11_rate_table[i] == val)
return BIT(i);
i++;
}
return 0;
}
It has several nominal style defects:
o compares different types (unsigned char to u8)
o uses a while loop and test of a known sized array
o array isn't declared static const
o array initialization is different style from others
in the same file. "type foo[] = { bar, baz };"
o the function argument is tested on the right side
tested on left side is more common.
So this could be transformed into something like:
int rtw_get_bit_value_from_ieee_value23a(u8 val)
{
int i;
static const u8 dot11_rate_table[] = {
2, 4, 11, 22, 12, 18, 24, 36, 48, 72, 96, 108
};
for (i = 0; i < ARRAY_SIZE(dot11_rate_table); i++) {
if (val == dot11_rate_table[i])
return BIT(i);
}
return 0;
}
Rakhi, do please strive to make the code "better" rather
than merely shut up checkpatch.
