Subject: [PATCH v2] USB: host: ehci-mxc: Add error handling in ehci_mxc_drv_probe()
Date: Wed, 13 May 2020 21:26:47 +0800 [thread overview]
Message-ID: <20200513132647.5456-1-tangbin@cmss.chinamobile.com> (raw)
The function ehci_mxc_drv_probe() does not perform sufficient error
checking after executing platform_get_irq(), thus fix it.
Fixes: 7e8d5cd93fa ("USB: Add EHCI support for MX27 and MX31 based boards")
