Huisong LiandGreg Kroah-Hartman f0d5624fbe mailbox: pcc: Reset pcc_chan_count to zero in case of PCC probe failure ...

[ Upstream commit 6d7d3c2874 ]

Currently, 'pcc_chan_count' is remains set to a non-zero value if PCC
subspaces are parsed successfully but something else fail later during
the initial PCC probing phase. This will result in pcc_mbox_request_channel
trying to access the resources that are not initialised or allocated and
may end up in a system crash.

Reset pcc_chan_count to 0 when the PCC probe fails in order to prevent
the possible issue as described above.
