Patches 1-4 are trivial, no-functional-change cleanups: convert the license boilerplate to an SPDX identifier, drop the redundant include (already pulled in via ), fix the missing space after a comma in a GENMASK_ULL() invocation, and use %u for the unsigned values in the existing registration debug message. Patch 5 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. Changes in v2: - Collected Reviewed-by from Radu on patches 1-3. - New patch 4: use %u for the unsigned values in the existing "Registering" debug message and fix its wording (Radu). - Patch 5: use %u for the unsigned values in the new messages (Radu), and write MSI/SPI in upper case to match patch 4. v1: https://lore.kernel.org/r/20260923083703.38974-1-farbere@amazon.com Eliav Farber (5): irqchip/alpine-msi: Use SPDX-License-Identifier irqchip/alpine-msi: Drop redundant asm/msi.h include irqchip/alpine-msi: Add missing space after comma in GENMASK_ULL irqchip/alpine-msi: Fix format and wording of the registration debug print irqchip/alpine-msi: Add debug logging for MSI allocation drivers/irqchip/irq-alpine-msi.c | 20 +++++++++++++------- 1 file changed, 13 insertions(+), 7 deletions(-) -- 2.47.3
