Subject: ACPI: PM: s2idle: Print type of wakeup debug messages
X-Git-Tag: v5.8-rc1~198^2~5
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=3441362b08dc16669adc0e7d3f3454ae38619229;p=thirdparty%2Flinux.git

ACPI: PM: s2idle: Print type of wakeup debug messages

Since acpi_s2idle_wake() knows the category of wakeup causing the
system to resume from suspend-to-idle, make it print a unique message
for each of them to help diagnose wakeup issues.
