Here are some spelling corrections for drivers/usb. cancelation -> cancellation succesful -> successful cancelation -> cancellation decriptor -> descriptor Initalize -> Initialize wierd -> weird Protocoll -> Protocol occured -> occurred successfull -> successful Procesing -> Processing devide -> divide Isochronuous -> Isochronous noticable -> noticeable Basicly -> Basically transfering -> transferring intialize -> initialize Incomming -> Incoming additionnal -> additional asume -> assume Unfortunatly -> Unfortunately retreive -> retrieve tranceiver -> transceiver Compatiblity -> Compatibility Incorprated -> Incorporated existance -> existence Ununsual -> Unusual Signed-off-by: Steven Cole <elenstev@mesatop.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
