Subject: ath5k: remove double cache alignment, ath_rxbuf_alloc() already does it
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=dd849782a7388e091e356373a744f8b7ae97188a;p=deliverable%2Flinux.git

ath5k: remove double cache alignment, ath_rxbuf_alloc() already does it

ath5k is using the (csz - 1) twice as ath_rxbuf_alloc() already allocates
and moves skb->data accordingly. Remove the extra (csz -1).
