Subject: [PATCH] ath10k: Fix qmi init error handling
Date: Wed,  6 Nov 2019 15:16:50 -0800	[thread overview]
Message-ID: <20191106231650.1580-1-jeffrey.l.hugo@gmail.com> (raw)

When ath10k_qmi_init() fails, the error handling does not free the irq
resources, which causes an issue if we EPROBE_DEFER as we'll attempt to
(re-)register irqs which are already registered.

Fixes: ba94c753ccb4 ("ath10k: add QMI message handshake for wcn3990 client")
