[ Upstream commit 5bd566703e16b17d17f4fb648440d54f8967462c ]
OA exponent value of 0 is a valid value for periodic reports. Allow user to pass 0 for the OA sampling interval since it gets converted to 2 gt clock ticks.
v2: Update the check in xe_oa_stream_init as well (Ashutosh) v3: Fix mi-rpc failure by setting default exponent to -1 (CI) v4: Add the Fixes tag
