From julia@diku.dk Wed Nov 12 14:37:20 2008 From: Julia Lawall Date: Sun, 9 Nov 2008 17:56:34 +0100 (CET) Subject: Staging: wlan-ng: p80211wext.c: use ARRAY_SIZE To: gregkh@suse.de Message-ID: From: Julia Lawall ARRAY_SIZE is more concise to use when the size of an array is divided by the size of its type or the size of its first element. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // @i@ @@ #include @depends on i using "paren.iso"@ type T; T[] E; @@ - (sizeof(E)/sizeof(E[...])) + ARRAY_SIZE(E) @depends on i using "paren.iso"@ type T; T[] E; @@ - (sizeof(E)/sizeof(T)) + ARRAY_SIZE(E) // Signed-off-by: Julia Lawall Signed-off-by: Greg Kroah-Hartman --- drivers/staging/wlan-ng/p80211wext.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) --- a/drivers/staging/wlan-ng/p80211wext.c +++ b/drivers/staging/wlan-ng/p80211wext.c @@ -122,7 +122,7 @@ static const long p80211wext_channel_fre 2412, 2417, 2422, 2427, 2432, 2437, 2442, 2447, 2452, 2457, 2462, 2467, 2472, 2484 }; -#define NUM_CHANNELS (sizeof(p80211wext_channel_freq) / sizeof(p80211wext_channel_freq[0])) +#define NUM_CHANNELS ARRAY_SIZE(p80211wext_channel_freq) /* steal a spare bit to store the shared/opensystems state. should default to open if not set */ #define HOSTWEP_SHAREDKEY BIT3 @@ -1787,7 +1787,7 @@ static iw_handler p80211wext_handlers[] }; struct iw_handler_def p80211wext_handler_def = { - .num_standard = sizeof(p80211wext_handlers) / sizeof(iw_handler), + .num_standard = ARRAY_SIZE(p80211wext_handlers), .num_private = 0, .num_private_args = 0, .standard = p80211wext_handlers,
