[2/2] raw/ioat: fix initial ring size check
Checks
Commit Message
When running the ioat_rawdev_autotest, the ring size was initially required
to be 0. This prevented the test being run multiple times, as the ring size
is modified to a non-zero value when running the first test.
A global variable is now used to track the expected ring size, and is used
in the initial value check. This enables the test to be run more than
once.
Fixes: 849470d522ed ("raw/ioat: add configure, start and stop functions")
