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. - 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.
