Subject: [PATCH] driver core: export device_is_bound() to fix build failure
Date: Fri,  6 Nov 2020 15:37:44 +0000	[thread overview]
Message-ID: <20201106153744.22661-1-sudipm.mukherjee@gmail.com> (raw)

When CONFIG_MXC_CLK_SCU is configured as 'm' the build fails as it
is unable to find device_is_bound(). The error being:
ERROR: modpost: "device_is_bound" [drivers/clk/imx/clk-imx-scu.ko]
	undefined!

Export the symbol so that the module finds it.
