--------------------------------
[ Upstream commit e96d52822f5ac0a25de78f95cd23421bcbc93584 ]
Commit 79ca6f74dae0 ("tpm: fix Atmel TPM crash caused by too frequent queries") has moved some code around without updating the error handling path.
This is now pointless to 'goto out_err' when neither 'clk_enable()' nor 'ioremap()' have been called yet.
Make a direct return instead to avoid undoing things that have not been done.
