Drivers: video: remove __dev* attributes. 2013-01-03T23:57:01+00:00 Greg Kroah-Hartman gregkh@linuxfoundation.org 2012-12-21T21:07:39+00:00 48c68c4f1b542444f175a9e136febcecf3e704d8 CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.
