From: Gertjan van Wingerde Date: Sun, 11 Apr 2010 12:31:10 +0000 (+0200) Subject: rt2x00: Refactor rt2800 version constants. X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8d0c9b65c904c6943566ccd2919c6a5ee6292c6b;p=linux-beck.git rt2x00: Refactor rt2800 version constants. The rt2800 version constants are inconsistent, and the version number don't mean a lot of things anyway. Refactor the constants to have some more meaningful names, and introduce and use some new helpers to check these chipset revisions. At the same time rename to revision, as they are more revision numbers rather than version numbers. Signed-off-by: Gertjan van Wingerde Acked-by: Ivo van Doorn Signed-off-by: John W.
