If anyone has any objections, please let me know. ------------------ From: Jeff Johnson [ Upstream commit 0293be2212d319d59589082461abf2a9b626cd1c ] Currently, during ath11k_service_ready_ext_event() processing, svc_rdy_ext.mac_phy_caps can be allocated during TLV parsing. This is a temporary allocation that is freed on the success path, but not on the error path. If parsing succeeds far enough to allocate mac_phy_caps and then fails on a later TLV, the allocation leaks. So free the allocation on the error path. Compile tested only.
