X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=6e1a63720228ef7fc3bd00b04dfb608064fbab4e;p=linux-2.6-omap-h63xx.git V4L/DVB (11091): cx18, ivtv: Ensure endianess for linemasks in VBI embedded in MPEG stream The sliced VBI payloads that cx18 and ivtv would insert in the MPEG stream did not have consistent endianess for the linemasks in the payload (a big endian platform would write them out big endian). This change ensures the linemasks are always stored as little-endian in the MPEG stream to ensure cross platform consistency in parsing the generated MPEG stream.
