This change moves the registration of indication call back after inquiring
the state of remote PD, this is logical flow since in any case just after
registration we are inquiring the state and doing client notification.
With existing arrangement of code, sometime there is occurring a race
condition between inquiring the remote pd state and indication call back.

Since the qmi service in snoc driver gets registered late,
it misses the first time FW ready is sent. This causes the
wait on FW ready to fail and eventually the driver loading fails.
Proceed with the driver initialization only once the FW ready
indication arrives. Handle error in case the wait for these
events timeout.

mmc clock scaling can be disabled/enabled through sysfs.
The present logic in this path deregisters/registers with devfreq
every time. Instead of this, we can simply suspend/resume the clock
scaling when requested for disabling/enabling clock scaling.
This patch updates the mentioned logic.
With original logic, observed deadlock between devfreq registration
and cmdqd thread in low memory conditions. The updated logic fixes
this deadlock condition aswell.

commit d25a01257e422a4bdeb426f69529d57c73b235fe upstream.
When the TIPC module is unloaded, we have identified a race condition
that allows a node reference counter to go to zero and the node instance
being freed before the node timer is finished with accessing it. This
leads to occasional crashes, especially in multi-namespace environments.
The scenario goes as follows:
CPU0:(node_stop) CPU1:(node_timeout) // ref == 2
1: if(!mod_timer())
2: if (del_timer())
3: tipc_node_put() // ref -> 1
4: tipc_node_put() // ref -> 0
5: kfree_rcu(node);
6: tipc_node_get(node)
7: // BOOM!
We now clean up this functionality as follows:
1) We remove the node pointer from the node lookup table before we
attempt deactivating the timer. This way, we reduce the risk that
tipc_node_find() may obtain a valid pointer to an instance marked
for deletion; a harmless but undesirable situation.
2) We use del_timer_sync() instead of del_timer() to safely deactivate
the node timer without any risk that it might be reactivated by the
timeout handler. There is no risk of deadlock here, since the two
functions never touch the same spinlocks.
3: We remove a pointless tipc_node_get() + tipc_node_put() from the
timeout handler.
