CHECK: Comparison to NULL could be written "!pwep"
147: FILE: drivers/staging/rtl8723bs/os_dep/ioctl_linux.c:442:
+			if (pwep == NULL)

CHECK: Comparison to NULL could be written "!skb"
226: FILE: drivers/staging/rtl8723bs/os_dep/recv_linux.c:204:
+	if (skb == NULL)

CHECK: Comparison to NULL could be written "!dvobj"
275: FILE: drivers/staging/rtl8723bs/os_dep/sdio_intf.c:398:
+	if (dvobj == NULL)
