USB: ohci: fix 2 timers to fire at jiffies + 1s
Code inspection discovered in 2 places timers were being incorrectly setup using round_jiffies_relative(HZ). The timer would then fire at time (0 <= T < HZ). Fix them to use round_jiffies(jiffies + HZ); Signed-off-by: Richard Kennedy <richard@rsk.demon.co.uk> Cc: Alan Stern <stern@rowland.harvard.edu> Cc: David Brownell <david-b@pacbell.net> Cc: Arjan van de Ven <arjan@infradead.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
