CHECK: Avoid using bool structure members because of possible alignment issues - see: https://lkml.org/lkml/2017/11/21/384
#417: FILE: drivers/staging/ks7010/ks_wlan.h:417:
+       bool is_device_open;

Introduced by commit a4c4c0492dad ("checkpatch: add a --strict test for
structs with bool member definitions"). If this is wrong, please feel
free to ignore it!

Thanks,
Nathan
