Use the helper function time_is_{before,after}_jiffies() to improve
code readability.

time_is_after_eq_jiffies checks at compile time that its argument is
unsigned long but ips_deny_time is u32 in the r8188eu driver.
We should change ips_deny_time to unsigned long, the rtl8723bs driver did
this as well. ips_deny_time is used in these places

pwrpriv->ips_deny_time = jiffies + rtw_ms_to_systime(ips_deffer_ms);
rtw_ms_to_systime converts milliseconds to jiffies and returns u32. We
should use msecs_to_jiffies instead, this functions returns unsigned long.
Do you want to have a go at this?

I see rtl8723bs/include/rtw_pwrctrl.h also has a definition of struct pwrctrl_priv on it,
which is unsigned long ips_deny_time.
Is there any difference, or should it be changed to unsigned long?
Thanks,
Wang

Hi Wang,
yes, I believe that we should change ips_deny_time to unsigned long.
But before this, we have to change rtw_ms_to_systime to msecs_to_jiffies.

Martin
