[ Upstream commit 4e19d51ca5b28a1d435a844c7b2a8e1b1b6fa237 ]
clang static analysis reports this problem:
cdv_intel_dp.c:2101:2: warning: Attempt to free released memory
kfree(gma_connector);
^~~~~~~~~~~~~~~~~~~~
In cdv_intel_dp_init() when the call to cdv_intel_edp_panel_vdd_off()
fails, the handler calls cdv_intel_dp_destroy(connector) which does
the first free of gma_connector. So adjust the goto label and skip
the second free.
Fixes: d112a8163f83 ("gma500/cdv: Add eDP support")
