tpm: Pull everything related to /dev/tpmX into tpm-dev.c
CLASS-dev.c is a common idiom for Linux subsystems This pulls all the code related to the miscdev into tpm-dev.c and makes it static. The identical file_operation structs in the drivers are purged and the tpm common code unconditionally creates the miscdev. Signed-off-by: Jason Gunthorpe <jgunthorpe@obsidianresearch.com> Reviewed-by: Joel Schopp <jschopp@linux.vnet.ibm.com> Reviewed-by: Ashley Lai <adlai@linux.vnet.ibm.com> [phuewe: tpm_dev_release is now used only in this file, thus the EXPORT_SYMBOL can be dropped and the function be marked as static. It has no other in-kernel users] Signed-off-by: Peter Huewe <peterhuewe@gmx.de>
