[PATCH 5.4 284/408] Input: imx6ul_tsc - clean up some errors in imx6ul_tsc_resume()

[Greg Kroah-Hartman]

From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

[ Upstream commit 30df23c5ecdfb8da5b0bc17ceef67eff9e1b0957 ]

If imx6ul_tsc_init() fails then we need to clean up the clocks.

I reversed the "if (input_dev->users) {" condition to make the code a
bit simpler.

Fixes: 6cc527b05847 ("Input: imx6ul_tsc - propagate the errors")
