Lars-Peter Clausen	a019e48cfb	kfifo: kfifo_copy_{to,from}_user: fix copied bytes calculation ... 'copied' and 'len' are in bytes, while 'ret' is in elements, so we need to multiply 'ret' with the size of one element to get the correct result.

Stefani Seibold	dfe2a77fd2	kfifo: fix kfifo_alloc() and kfifo_init() ... Fix kfifo_alloc() and kfifo_init() to alloc at least the requested number of elements. Since the kfifo operates on power of 2 the request size will be rounded up to the next power of two.
