w1: fix for loop exit condition in w1_seq_show()
The W1_42_FINISHED_BYTE is 0xFF so the cast means the condition is never true. Fixes: d9411e57dc7f ('w1: Add support for DS28EA00 sequence to w1-therm') Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
