Well your patch looked reasonable, except it muddies the CONFIG_foo
namespace. So could you rework it thusly:


- Change all instances of

#ifdef CONFIG_HDLC
<stuff>
#endif

to

#ifdef HDLC_ENABLED
<stuff>
#endif


then do

#if defined(CONFIG_HDLC) || (defined(CONFIG_HDLC_MODULE) && defined(CONFIG_SYNCLINK_MODULE))
#define HDLC_ENABLED
#endif
or whatever?



Or, better, (but semi off-topic):


#if HDLC_ENABLED
<stuff>
#endif

#if defined(CONFIG_HDLC) || (defined(CONFIG_HDLC_MODULE) && defined(CONFIG_SYNCLINK_MODULE))
#define HDLC_ENABLED 1
#else
#define HDLC_ENABLED 0
#endif
Because then a) you'll get a warning if someone already defined
HDLC_ENABLED and b) you'll get a warning if you mistype `#if HLDC_ENABLED'
