+Subject: common: fix potential NULL dereference in print_rss_hkey()
+
+Static analyzer (Svace) reported a possible null pointer dereference
+in print_rss_hkey(). Specifically, when the 'hkey' pointer is NULL,
+the function continues execution after printing an error message,
+leading to dereferencing hkey[i].
+
+This patch adds an early return after the NULL check to prevent
+execution from continuing in such cases.
+
+This resolves:
+DEREF_AFTER_NULL: common.c:209
+
+Found by Svace static analysis tool.
