drivers/staging/esp8089/esp_mac80211.c:596:33-34: WARNING comparing pointer to 0
Compare pointer-typed values to NULL rather than 0
Semantic patch information:
This makes an effort to choose between !x and x == NULL. !x is used
if it has previously been used with the function used to initialize x.
This relies on type information. More type information can be obtained
using the option -all_includes and the option -I to specify an
include path.
