Subject: of/overlay: Remove unused variable
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d3a891652adb82e1973348c703a597cb54e41dea;p=linux-beck.git

of/overlay: Remove unused variable

Commit 3e7f7626fd49a ("of/overlay: Do not generate duplicate nodes") removed
the only use of the 'grandchild' variable, which leads to the following build
warning:

drivers/of/overlay.c: In function 'of_overlay_apply_single_device_node':
drivers/of/overlay.c:89:31: warning: unused variable 'grandchild' [-Wunused-variable]
  struct device_node *tchild, *grandchild;
                               ^

Remove this unused variable.
