Public bug reported:
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.
[Fix]
* Clean cherry-picks of the following upstream patches:
* 3c03c49b2fa5: "Coresight: Introduce a new struct coresight_path"
* d87d76d823d1: "Coresight: Allocate trace ID after building the path"
* 080ee83cc361: "Coresight: Change functions to accept the coresight_path"
[Test Plan]
* Compile tested
[Regression potential]
* Changes are localized to coresight. Possible regressions could result
in unexpected behavior of coresight module.
