Subject: [PATCH net-next] ath10k: fix possible memory leak in ath10k_bmi_lz_data_large()
Date: Mon, 27 Apr 2020 10:43:48 +0000	[thread overview]
Message-ID: <> (raw)

'cmd' is malloced in ath10k_bmi_lz_data_large() and should be freed
before leaving from the error handling cases, otherwise it will cause
memory leak.

Fixes: d58f466a5dee ("ath10k: add large size for BMI download data for SDIO")
