Patches 1-3 are trivial, no-functional-change cleanups that address the coding-style issues checkpatch reports for the file: convert the license boilerplate to an SPDX identifier, drop the redundant include (already pulled in via ), and fix the missing space after a comma in a GENMASK_ULL() invocation. Patch 4 adds an info message on successful initialisation and debug messages on the MSI interrupt allocation and free paths, to make it easier to follow the driver flow when debugging. Build-tested for arm64 with the aarch64 toolchain and KCFLAGS=-Werror. The driver is used by the Alpine V2, Alpine V3 and AL8 SoCs.
