Subject: [PATCH] mt7601u: add missing release on skb in mt7601u_mcu_msg_send
Date: Sat, 18 Jul 2020 00:26:29 -0500 [thread overview]
Message-ID: <20200718052630.11032-1-navid.emamdoost@gmail.com> (raw)
In the implementation of mt7601u_mcu_msg_send(), skb is supposed to be
consumed on all execution paths. Release skb before returning if
test_bit() fails.
