From: Michael Krufky Date: Mon, 22 Jan 2007 05:17:55 +0000 (-0300) Subject: V4L/DVB (5169): Pvrusb2: Use macro names for FX2 commands X-Git-Tag: v2.6.21-rc2~66^2~61 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=8d3643637e18e6590969436734c22151805d0350;p=linux-2.6-omap-h63xx.git V4L/DVB (5169): Pvrusb2: Use macro names for FX2 commands This is a maintainability cleanup; use nice names for all the FX2 commands instead of raw bytes. This way we can easily find where we issue FX commands.
