[v2] staging: rtl8723bs: simplify NULL pointer checks

[PATCH v2] staging: rtl8723bs: simplify NULL pointer checks

Posted by Mohammed Sohail 2 weeks, 4 days ago

Replace ptr == NULL with !ptr in rtw_recv.h and ioctl_cfg80211.c.

Improves readability and follows kernel coding style.
No functional changes.
