From: Malcolm Priestley Date: Fri, 14 Aug 2015 21:58:50 +0000 (+0100) Subject: staging: vt6655: replace typedef struct tagDEVICE_TD_INFO and structure X-Git-Tag: firefly_0821_release~176^2~1221^2~24 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=543828599afc9cdd9012e363c7393e5ed102aa2a;p=firefly-linux-kernel-4.4.55.git staging: vt6655: replace typedef struct tagDEVICE_TD_INFO and structure Create struct vnt_td_info with members mic_hdr skb buf buf_dma dwReqCount -> req_count byFlags -> flags In struct tagSTxDesc volatile is removed because it will generate a warning (in any case this member is not) and renaming td_info.
