Now I checked with checkpatch, and it complained a few things: WARNING: Block comments use a trailing */ on a separate line #168: FILE: sound/pci/hda/hda_acpi.c:79: + * devm_platform_get_and_ioremap_resource() */ ERROR: code indent should use tabs where possible #182: FILE: sound/pci/hda/hda_acpi.c:93: +^I IRQF_SHARED, KBUILD_MODNAME, azx);$ ERROR: code indent should use tabs where possible #308: FILE: sound/pci/hda/hda_acpi.c:219: +^I THIS_MODULE, 0, &hda->card);$ WARNING: Prefer "GPL" over "GPL v2" - see commit bf7fbeeae6db ("module: Cure th) #405: FILE: sound/pci/hda/hda_acpi.c:316: +MODULE_LICENSE("GPL v2"); Care to address those and resubmit? thanks, Takashi
