If anyone has any objections, please let me know. ------------------ From: Loic Poulain [ Upstream commit 2e9c1da4ee9d0acfca2e0a3d78f3d8cb5802da1b ] ath10k_wmi_cmd_send takes ownership of the passed buffer (skb) and has the responsibility to release it in case of error. This patch fixes missing free in case of early error due to unhandled WMI command ID.
