[PATCH] kernel-shark: Add quotes around $XDG_SESSION_TYPE in kshark-su-record

[PATCH] kernel-shark: Add quotes around $XDG_SESSION_TYPE in kshark-su-record

[Steven Rostedt]

From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>

If XDG_SESSION_TYPE is not set, then $XDG_SESSION_TYPE will become nothing,
which means the test:

 if [ $XDG_SESSION_TYPE = "wayland" ];

turns into

 if [  = "wayland" ];

And will cause a shell error. Adding quotes around "$XDG_SESSION_TYPE"
changes an empty $XDG_SESSION_TYPE into:

 if [ "" = "wayland" ];

which the shell can understand.
