Bug description:
SRU Justification
[Impact]
* Inclusion of upstream f6028eeeb5e4: "coresight: core: Disable helpers for
devices that fail to enable" added two calls to coresight_disable_helpers()
with an additional path parameter, which is not available in the current
function call, which only accepts coresight_disable_helpers(struct
coresight_device *csdev). This causes the kernel to fail to build when
coresight is enabled.
* Additionally, upstream 53b9e2659719: "coresight: holding cscfg_csdev_lock
while removing cscfg from csdev" caused build failures with a spinlock type
change.
[Fix]
* Clean cherry-pick of upstream 3c03c49b2fa5: "Coresight: Introduce a new
struct coresight_path"
* Backport of upstream 080ee83cc361: "Coresight: Change functions to accept
the coresight_path"
* Clean cherry-pick of upstream 26f060c106f6: "coresight: change
coresight_device lock type to raw_spinlock_t"
[Test Plan]
* Compile tested
[Regression potential]
* Changes are localized to coresight. Possible regressions could
result in unexpected behavior of coresight module.
