[PATCH 10/11] Bluetooth: btmrvl_sdio: Do not free HCI_VENDOR_PKT frame by hci_recv_frame()

From: Zijun Hu

Date: Sat Jul 25 2026 - 04:59:25 EST


For a HCI_VENDOR_PKT frame, hci_recv_frame() does not accept it and
will kfree_skb() it directly.

But btmrvl_sdio_card_to_host() is still calling hci_recv_frame() for
the frame.

Fix by freeing it with kfree_skb() directly.
