This patch set includes the cleanup and bug fixes patches, previously
part of the "tpm: add the securityfs pseudo files support for TPM 2.0
firmware event log" patch set, in order to upstream them more quickly.

Changelog History

v5:

- Moved cleanup/fixes patches into this patch set.
- Patch "fix the race condition between event log access and chip
getting unregistered"
  - updated subject line and commit description.
  - modified fops code to use chip kref.
  - modified fops to lock inode before accessing inode private data.
  - renamed tpm_securityfs_data to tpm_chip_seqops, as it no more
    holds bios log, but associates seqops with respective chip. For
    the same reason, moved it to tpm.h
- Patch "replace or remove printk error messages"
  - cleaned up dev_dbg and used dev_info as applicable.

v4:

- Includes feedbacks from Jarkko and Jason.
- Patch "tpm: define a generic open() method for ascii & bios
measurements".
  - Fix indentation issue.
- Patch "tpm: replace the dynamically allocated bios_dir as
struct dentry array".
  - Continue to use bios_dir_count variable to use is_bad() checks and
    to maintain correct order for securityfs_remove() during teardown.
  - Reset chip->bios_dir_count in teardown() function.
- Patch "tpm: validate the event log access before tpm_bios_log_setup".
  - Retain TPM2 check which was removed in previous patch.
  - Add tpm_bios_log_setup failure handling.
  - Remove use of private data from v3 version of patch. Add a new
  member to struct tpm_chip to achieve the same purpose.
- Patch "tpm: redefine the read_log method to check for ACPI/OF 
properties sequentially".
  - Move replacement of CONFIG_TCG_IBMVTPM with CONFIG_OF to
  this patch from patch 3.
  - Replace -1 error code with -ENODEV.
- Patch "tpm: replace the of_find_node_by_name() with dev of_node
property".
  - Uses chip->dev.parent->of_node.
  - Created separate patch for cleanup of pr_err 
  messages.
- Patch "tpm: remove printk error messages".
  - New Patch.
- Patch "tpm: add the securityfs file support for TPM 2.0 event log".
  - Parses event digests using event alg_id rather than event log header
    alg_id.
  - Uses of_property_match_string to differentiate tpm/vtpm compatible
    property.
  - Adds the comment for difference in tpm/vtpm endianness.

v3:

- Includes the review feedbacks as suggested by Jason.
- Split of patches into one patch per idea.
- Generic open() method for ascii/bios measurements.
- Replacement of of **bios_dir with *bios_dir[3].
- Verifying readlog() is successful before creating securityfs entries.
- Generic readlog() to check for ACPI/OF in sequence.
- read_log_of() method now uses of_node propertry rather than
  calling find_device_by_name.
- read_log differentiates vtpm/tpm using its compatible property.
- Cleans pr_err with dev_dbg.
- Commit msgs subject line prefixed with tpm.

v2:

- Fixes issues as given in feedback by Jason.
- Adds documentation for device tree.
