clk_prepare_enable() may fail, so we better check its return value and
propagate it in the case of error.

<title>Input: touchscreen - drop unnecessary calls to device_init_wakeup</title>

Calling device_init_wakeup in the remove function is unnecessary since the
device is going away, and thus won't be able to cause any wakeups under any
circumstances. Besides, the driver cleanup code already handles the
necessary cleanup.

Similarly, disabling wakeup in the probe error path is unnecessary, as is
disabling wakeup in the probe function in the first place.

If common clock framework is configured, the driver generates a warning,
which is fixed by this change:

None of these files are actually using any __init type directives
and hence don't need to include &lt;linux/init.h&gt;.  Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.
