[ Upstream commit 9a70551996e699fda262e8d54bbd41739d7aad6d ]
Leaving wakeup enabled during probe fail (-EPROBE_DEFER) or remove makes the subsequent probe fail.
[ 3.749454] remoteproc remoteproc0: releasing 3000000.remoteproc [ 3.752949] qcom_q6v5_pas: probe of 3000000.remoteproc failed with error -17 [ 3.878935] remoteproc remoteproc0: releasing 4080000.remoteproc [ 3.887602] qcom_q6v5_pas: probe of 4080000.remoteproc failed with error -17 [ 4.319552] remoteproc remoteproc0: releasing 8300000.remoteproc [ 4.332716] qcom_q6v5_pas: probe of 8300000.remoteproc failed with error -17
Fix this by disabling wakeup in both cases so the driver can properly probe on the next try.
