[ Upstream commit 7bcceb4c9896b1b672b636ae70fe75110d6bf1ad ]
omap_sham_probe() calls pm_runtime_get_sync() and calls pm_runtime_put_sync() latter to put usage_counter. However, pm_runtime_get_sync() will increment usage_counter even it failed. Fix it by replacing it with pm_runtime_resume_and_get() to keep usage counter balanced.
