invalid use of void expression

[koryphaee]

This line:

rtl8723au_bt/btusb.c

Line 1747 in cdb5515

*skb_put(skb, 1) = 0x00;

gives me a warning "dereferencing 'void *' pointer" and an error "invalid use of void expression" when I try to make. I use Void Linux with the kernel 4.15.9_1, gcc is version 7.3.0 and my bluetooth/wifi chip is RTL8723BE.

It compiles if you change the line to this: *(ushort*)skb_put(skb, 1) = 0x00;
