Allow to build coresight as modules. This gives developers the feasibility to
test their code without reboot.
This series is based on below two series.
- "coresight: allow to build components as modules"
https://lkml.org/lkml/2018/6/5/989
- "coresight: make drivers modular"
https://lkml.org/lkml/2020/1/17/468
Change from v5:
Add below CTI clean up change from Mike into series
-https://lists.linaro.org/pipermail/coresight/2020-July/004349.html
Increase module reference count when enabling CTI device (Mike)
Change from v4:
Fix error handling in coresight_grab_devicei() (Greg)
Add coresight: cti: Fix remove sysfs link error from Mike
-https://lists.linaro.org/pipermail/coresight/2020-July/004275.html
Move cti_remove_conn_xrefs() into cti_remove() (Mike)
Align patch subject to coresight: <component>: <description> (Mike)
Change from v3:
Rebase to coresight-next (Mike and Mathieu)
Reorder try_get_module() (Suzuki)
Clean up etmdrvdata[] in device remote path (Mike)
Move cti_remove_conn_xrefs to cti_remove (Mike)
Change from v2:
Rebase to 5.8-rc5. Export coresight_add_sysfs_link and
coresight_remove_sysfs_link
Fix one cut and paste error on MODULE_DESCRIPTION of CTI
Change from v1:
Use try_module_get() to avoid module to be unloaded when device is used
in active trace session. (Mathieu P)
Change from above two series.
This series adds the support to dynamically remove module when the device in
that module is enabled and used by some trace path. It disables all trace
paths with that device and release the trace path.
