staging: rtl8192e: replace explicit NULL comparison
Replace explicit NULL comparison with ! operator to simplify code. Found with Coccinelle script: @@ expression ptr; position p; statement s0, s1; @@ ptr@p = \(kmalloc\|devm_kzalloc\|kmalloc_array\|devm_ioremap\|usb_alloc_urb\| alloc_netdev\|dev_alloc_skb\)(...) ... when != ptr if ( ( + ! ptr - == NULL ) ) s0 else s1 Signed-off-by: Gargi Sharma <gs051095@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
