Subject: [PATCH v2 0/3] fix leaks in some WMI error path
Date: Wed,  6 May 2026 15:42:37 +0200	[thread overview]
Message-ID: <20260506134240.2284016-1-nico.escande@gmail.com> (raw)

So this is similar work to what has been posted here [0] for ath12k.

When we use the pattern 'return ath11k_wmi_cmd_send(...)' without
explicitly checking the return value we fail to free the allocated skb.

This has been split into 2 patches per Jeff's guidance to hopefully
ease the backporting process.
