Subject[PATCH AUTOSEL 5.7 218/274] ice: Fix resource leak on early exit from function
Date
From: Eric Joyner <eric.joyner@intel.com>

[ Upstream commit 857a4f0e9f4956fffc0cedcaa2ba187a2e987153 ]

Memory allocated in the ice_add_prof_id_vsig() function wasn't being
properly freed if an error occurred inside the for-loop in the function.

In particular, 'p' wasn't being freed if an error occurred before it was
added to the resource list at the end of the for-loop.
