staging: wlan-ng: simplify NULL tests
Replace direct comparisons to NULL i.e. 'x == NULL' with '!x' for consistency. Coccinelle semantic patch used: @@ identifier func; expression x; statement Z; @@ x = func(...); if ( ( + ! x - == NULL | + ! - NULL == x ) ) Z Signed-off-by: Eva Rachel Retuya <eraretuya@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
