Subject: [PATCH] staging: wilc1000: check if device is initialzied before changing vif
Date: Mon, 28 Oct 2019 18:40:26 +0000	[thread overview]
Message-ID: <20191028184019.31194-1-adham.abozaeid@microchip.com> (raw)

From: Adham Abozaeid <adham.abozaeid@microchip.com>

When killing hostapd, the interface is closed which deinitializes the
device, then change virtual interface is called.
This change checks if the device is initialized before sending the
interface change command to the device
