[PATCH 394/510] staging: brcm80211: remove macro usage for sk_buff release
Greg Kroah-Hartman
gregkh at suse.de
Mon Jan 10 20:41:58 UTC 2011
From: Arend van Spriel <arend at broadcom.com>
PKTFREE macro calls osl_pktfree. This function has been renamed to
pkt_buf_free_skb as it comprises of functionality additional to
dev_kfree_skb(_any) function and to get rid of the OSL concept in
this driver.
