This series fixes some bugs in remoteproc error paths. The last
patch is derived from something I posted before, but has been
updated to based on Linus' current master branch.

By this time the rproc device type has been assigned, with rproc_type_release() as the release function. The first thing rproc_type_release() does is call: idr_destroy(&rproc->notifyids); But at the time the ida_simple_get() call is made, the notifyids field in the remoteproc structure has not been initialized. I'm not actually sure this case causes an observable problem, but it's incorrect. Fix this by initializing the notifyids field before calling ida_simple_get() in rproc_alloc().

Fix this by having that call be reached through a different label. Additionally, if qcom_add_sysmon_subdev() returns an error, the subdevs that had already been added will not be properly removed. Fix this by having the added subdevs (including the IPA notify one) be removed in this case. Finally, arrange for the sysmon subdev to be removed before the rest in the event rproc_add() returns an error. Have cleanup activity done in q6v5_remove() be done in the reverse order they are set up in q6v5_probe() (the same order they're done in the q6v5_probe() error path). Use a local variable for the remoteproc pointer, which is used repeatedly. Remove errant semicolons at the end of two function blocks.
