[PATCH] ARM: OMAP1: Fix error handling path in omap1_dm_timer_init()

[Christophe JAILLET]

platform_device_put() should be called instead of
platform_device_unregister() in the error handling path because, at this
point, no successful platform_device_add() has been called.

While at it, change the goto label if kzalloc() fails. It is harmless to
call 'kfree(NULL)', but it is also pointless.

This is a speculative patch, not even compile tested because of lack of
cross-compiler.
So review with care.
