[PATCH] swsusp: Do not fail if resume device is not set
In the kernels later than 2.6.19 there is a regression that makes swsusp
fail if the resume device is not explicitly specified.
It can be fixed by adding an additional parameter to
mm/swapfile.c:swap_type_of() allowing us to pass the (struct block_device
*) corresponding to the first available swap back to the caller.
