[SRU][P:linux, N:linux-azure-nvidia-6.14][PATCH 0/2] Kernel fails to build when coresight is enabled

[John Cabaj]

BugLink: https://bugs.launchpad.net/bugs/2122527

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-pick of upstream 3c03c49b2fa5: "Coresight: Introduce a new struct coresight_path"
* Backport of upstream 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.
