coresight: Fixes device's owner field for registered using coresight_init_driver()
[ Upstream commit 9f52aecc952ddf307571517d5c91136c8c4e87c9 ]
The coresight_init_driver() of the coresight-core module is called from
the sub coresgiht device (such as tmc/stm/funnle/...) module. It calls
amba_driver_register() and Platform_driver_register(), which are macro
functions that use the coresight-core's module to initialize the caller's
owner field. Therefore, when the sub coresight device calls
coresight_init_driver(), an incorrect THIS_MODULE value is captured.
The sub coesgiht modules can be removed while their callbacks are
running, resulting in a general protection failure.
Add module parameter to coresight_init_driver() so can be called
with the module of the callback.
Fixes: 075b7cd7ad7d ("coresight: Add helpers registering/removing both AMBA and platform drivers")
