ACPI: Reduce ACPI resource conflict message to KERN_WARNING, printk cleanup (1638bca8) · Commits · 戴 / test

By default, ACPI resource conflict messages are logged at level KERN_ERR. This is a rather high level for a message that is more a warning than an indication of a real kernel error. Also, KERN_ERR level messages can appear over some boot splash screens, and this message is not serious enough to warrant such treatment. Thus, the log level has been reduced to KERN_WARNING. [lenb changed to KERN_WARNING rather than all the way to KERN_INFO] Also, cleanup message to use %pR resource printing format. Signed-off-by:
