From: Julia Lawall <julia@xxxxxxx> 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/) // <smpl> @i@ @@ #include <linux/kernel.h> @depends on i using "paren.iso"@ type T; T[] E; @@ - (sizeof(E)/sizeof(E[...])) + ARRAY_SIZE(E) // </smpl> Signed-off-by: Julia Lawall <julia@xxxxxxx> --- drivers/net/wireless/ath9k/rc.c | 6 ++---- 1 files changed, 2 insertions(+), 4 deletions(-) diff --git a/drivers/net/wireless/ath9k/rc.c b/drivers/net/wireless/ath9k/rc.c index cca2fc5..ea37673 100644 --- a/drivers/net/wireless/ath9k/rc.c +++ b/drivers/net/wireless/ath9k/rc.c @@ -1272,8 +1272,7 @@ static void ath_rc_update_ht(struct ath_softc *sc, rate_ctrl->state[tx_rate].per = 100; } else { /* xretries == 2 */ - count = sizeof(nretry_to_per_lookup) / - sizeof(nretry_to_per_lookup[0]); + count = ARRAY_SIZE(nretry_to_per_lookup); if (retries >= count) retries = count - 1; /* new_PER = 7/8*old_PER + 1/8*(currentPER) */ @@ -1291,8 +1290,7 @@ static void ath_rc_update_ht(struct ath_softc *sc, } else { /* xretries == 0 */ /* Update the PER. */ /* Make sure it doesn't index out of array's bounds. */ - count = sizeof(nretry_to_per_lookup) / - sizeof(nretry_to_per_lookup[0]); + count = ARRAY_SIZE(nretry_to_per_lookup); if (retries >= count) retries = count - 1; if (info_priv->n_bad_frames) { -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
