Subject: [PATCH] fix(resume): check for presence of /sys/power/resume

On platforms where the kernel is built without suspend/resume support we
|
|
see "cat: /sys/power/resume: No such file or directory" message when
|
|
creating an initrd image. Check for the presence of /sys/power/resume
|
|
first before reading it.
