Do you want me to create a function *like* tpm_chip_find_get() that 
takes an additional parameter whether to get the ops semaphore and have 
that function called by the existing tpm_chip_find_get() and the new 
tpm_chip_find(). The latter would then not get the ops semphore. I 
didn't want to do this since one time the function returns with a lock 
held and the other time not.
