interconnect: icc-clk: check return values of devm_kasprintf()

2024-12-17T12:03:34Z

devm_kasprintf() can fail and return NULL, add missing return value checks.

interconnect: qcom: icc-rpm: Set the count member before accessing the flex array

2024-12-17T12:03:02Z

The following UBSAN error is reported during boot on the db410c board on a clang-19 build: Internal error: UBSAN: array index out of bounds: 00000000f2005512 [#1] PREEMPT SMP ... pc : qnoc_probe+0x5f8/0x5fc ... The cause of the error is that the counter member was not set before accessing the annotated flexible array member, but after that. Fix this by initializing it earlier.

interconnect: Use of_property_present() for non-boolean properties

Add driver for the Qualcomm interconnect buses found in QCS8300 based platforms. The topology consists of several NoCs that are controlled by a remote processor that collects the aggregated bandwidth for each master-slave pairs.

interconnect: Switch back to struct platform_driver::remove()

2024-10-22T09:34:18Z

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/interconnect to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.
